HLN58 (ZN85B) -40.5 solid sealed vacuum circuit breaker

1. Overview:

HLN58 ZN85B -40.5ZN85B-40.5 indoor and outdoor vacuum breaker is my company in the ZN85 (3AV3) based, absorption VS1 spring operating mechanism characteristics, combined with the operation of the practical design and production of new type circuit breaker. This product applicable to the rated voltage of 40.5kV, three-phase AC 50Hz indoor high voltage equipment, for industrial and mining enterprises, power plant and substation control and protection of electrical equipment as and applicable in places with frequent operation.

Circuit breaker the arc before and after the arc chamber and operating mechanism of layout structure, effectively reduce the depth of the circuit breaker. The organic composite insulating material, in ZN85 on the basis of increasing the touch arm insulated, design more compact, further reducing the volume of circuit breaker; leading electric circuit and the vacuum interrupter connected directly, and the electrical connection is more reliable.

Two. Standard

HLN58 (ZN85B) -40.5KV vacuum circuit breaker is in compliance with GB1984-2003, GB/T11022 and other related standards.

Three. Main features:

There is a complete anti false operation interlock to ensure the safety of personnel and equipment, easy to operate, easy to maintain.

Operating mechanism is arranged in the vacuum arc extinguishing chamber in front of the chassis in, its operational performance and arc quenching chamber opening and closing performance more consistent, reducing the unnecessary intermediate links, the circuit breaker performance more reliable

The overall layout of the circuit breaker is reasonable, beautiful and simple.

Adopt the improved lead screw propulsion mechanism, labor saving, smooth, self - locking performance is good.

Four. Operating mechanism

HLN58 (ZN85B) operating mechanism using the same form of VS1 spring operating mechanism, with a relatively simple structure, reliable and mature, long life, low maintenance and so on.

Five. Installation method

HLN58 (ZN85B) vacuum circuit breaker in the switch cabinet can be installed in the form of fixed, can also be drawn out, with good compatibility.

Floor the handcart type breaker mainly 1400mm KYN61 centrally mounted and KYN61B type cabinet, fixed type circuit breaker is equipped with XGN-40.5, GG1A-40.5 and box type substation etc..

Six ZN85B (.HLN58) -40.5 solid sealed vacuum circuit breaker operating conditions:

6.1 ambient air temperature: not more than 40 DEG C; the average temperature does not exceed 35 degrees; the lowest air temperature is - 25 DEG C.

6.2 air relative humidity: daily average of not more than 95%, the average monthly value of not more than 90%; water vapor pressure daily average value is not greater than 2.2kPa; monthly average value is not more than 1.8kPa;

6.3 altitude: no more than 1000m;

6.4 there is no obvious contamination by dust, smoke, corrosion and / or flammable gas, steam or salt mist;

6.5 from the switchgear and control equipment of external vibration or earthquake can be ignored;

6.6 the amplitude of electromagnetic interference in the two system is not more than 1.6kV.

Structure and working principle of seven -40.5 (.HLN58) ZN85B solid sealed vacuum circuit breaker:

Reliable and modular spring operating mechanism of Zn] - 40.5 series of indoor high voltage vacuum circuit breaker spring operating mechanism for the arrangement of the spring operating mechanism, with the manual energy storing and electric energy storage function, the whole shape, small size, good integral rigidity of the circuit breaker, operation performance from the beginning to the end a transmission reliability have tens of thousands of production, operating experience, the stability of the whole breaker action, high reliability. The main circuit using the sleeve structure in the form of a ZN85B-40.5 sealing type indoor high voltage vacuum circuit breaker main circuit sleeve type structure form.

A vacuum circuit breaker main circuit interrupter is arranged in a sealed insulating cylinder, an insulating cylinder by using epoxy resin materials of mechanical and electrical reliability, and the use of advanced APG process, the insulating cylinder is installed and play a supporting role, and the insulation design of the insulation tube relative to the full. Considering the requirements of national standards and harsh working conditions, can not only prevent is not influenced by the external environment vacuum chamber, to prevent dust and foreign bodies into the main circuit part, and can ensure that even in the humid environment and serious pollution, can also show high resistance to voltage standard switching effect. The function module of the modular design of spring operating mechanism is ZN - indoor vacuum circuit breaker is another feature, the spring operating mechanism includes closing and opening the two functional modules, it has convenient maintenance, replacement fast, power plug repair time Short features. In addition, as for the spare parts of the switching function modules have been with special grease lubrication and adjustment and has a long shelf life, and suitable to switch module replacement after without the circuit breaker operating mechanism to adjust, and do not change the circuit breaker dynamic characteristics, maintenance will be reduced to * * * little. Fault switching module manufacturing plant maintenance and maintenance can also as a spare part.

Implementation of convenient handcart between exchange HLN58 ZN85B - 40.5 solid seal type indoor high voltage vacuum circuit breaker handcart type dimensions and zn85-40.5 handcart type vacuum circuit breaker is smaller and, and its adaptability, for a wide range of.HLN58 (ZN85B), - 40.5 sealing type indoor high voltage vacuum break circuit breaker adopts a floor type structure design and built-in structure design, built-in with the transport vehicle can and is convenient for the users of on-site maintenance and periodic maintenance, HLN58 ZN85B - 40.5 solid seal type indoor high voltage vacuum circuit breaker adapter cabinet type for KYN61-40.5 high voltage switchgear cabinet.

The main circuit adopts the sleeve type or sealing type structure of HLN58 (ZN85B) main circuit -40.5 sealed indoor high voltage vacuum circuit breaker with sleeve and sealing structure of two kinds of forms for users to easily select according to different places. The use of sleeve type structure: a leading power vacuum circuit breaker the interrupter is arranged in a sealed insulating cylinder, an insulating cylinder by using epoxy resin materials of mechanical and electrical reliability, and the use of advanced APG process, the insulating cylinder is installed and play a supporting role, and the insulation design of the insulation tube relatively. The full consideration of the requirements of national standards and harsh working conditions, can not only prevent is not influenced by the external environment vacuum chamber, to prevent dust and foreign bodies into the main circuit part, and can ensure that even in the humid environment and serious pollution, but also can be used for electric The pressure effect exhibits a high resistance.

HLN58 (ZN85B) a conductive loop -40.5 sealed indoor high voltage vacuum circuit breaker using sealed pole solid insulation technology, the embedded pole through the automatic pressure setting advanced APG technology to other parts of the vacuum interrupter and a conductive circuit directly sealed in special epoxy resin material. The formation of a main electric circuit module. The sealed pole mounted end designed double skirt, the pole has a large creepage distance, high mechanical strength, high precision parts, fewer parts, no need to adjust the two characteristics, the lap surface less. The pole electric field distribution, avoid the local electric field concentration of organic insulation damage. At the same time the structure of the design can be greatly simplified, a main circuit of the assembly process, completely avoid the problem of the main circuit and the connecting bolt loosening due to vibration in the operation, ensure the dominant power Circuit connection of high reliability, so that the circuit breaker of a leading electrical circuit to achieve maintenance free.

Flexible installation HLN58 ZN85B - 40.5 sealing type indoor high voltage vacuum circuit breaker with the fixed type and handcart type two kinds of installation, can conveniently realize reliable mechanical "five anti interlocking". Both can be directly installed in various types of fixed type switch cabinet. Can also be equipped with installed in various types of movable type switch cabinet handcart.
