2.3 the installation height of the cable head is above 850mm;

2.4 can be added to the user's requirements of lightning arrester.

3 busbar room

3.1 using rectangular cross section or tubular insulated busbar;

3.2 adjacent cabinets is separated by a wall bushing, limiting the fault arc spreading, to avoid the accident;

3.3 busbar joint sets of SMC material to strengthen the level of insulation between the busbar and make it more reliable.

Two 4 meter room

4.1 the internal use of mesh type mounting plate, easy to install and replace various types of relays;

4.2 can use the integrated microcomputer to protect the equipment to realize the remote control system (background) control.

Two 5 plugs (block)

Handcart and a cabinet body between the auxiliary circuit connecting wire is arranged on the handcart plugs and installed on the socket body through, the cart is pushed into the test position will plug, the auxiliary circuit will be put into operation. Hand car back to the test location when the plug and unplug, the handcart can continue to pull to the outside of the cabinet, the plug socket with the handcart with interlocking device.

6 hand car

6.1 the truck frame is made of high-quality steel plate bending welding and, according to use, the truck can be divided into circuit breaker handcart, fuse, isolation handcart, voltage transformer hand trolley and arrester handcart, circuit breaker using domestic zn85-40.5 3AV3 of vacuum breaker and the French Schneider SF1, SF2 and Alston FP series hexafluoride sulphur circuit breaker device, with beautiful appearance, small volume, high operation reliability, long life and so on, the screw propulsion mechanism, energy balance and self-locking performance.

6.2 ZN85-40.5 (3AV3) circuit breaker characteristics

The 6.2.1 circuit breaker adopts the arc extinguishing chamber on the upper and the operating mechanism in the whole arrangement of the structure, which is beneficial for debugging;

6.2.2 uses air and organic composite insulation structure, the design is compact and light weight;

6.2.3 can be equipped with the United States Cutler-Hammer company, SIEMENS and domestic vacuum arc extinguishing chamber, three kinds of arc extinguishing chamber can use the cup longitudinal magnetic field arc, low closure, non symmetrical breaking performance is good, can meet the needs of different users;

6.2.4 simple spring operating mechanism, mechanical life 10000 times;

6.2.5 large distance insulation insulation design, the inner wall of the insulation tube for the umbrella skirt structure, operating performance under the condition of pollution is stable and reliable.

Characteristics of 6.3 SF2 type six sulfur fluoride circuit breaker

6.3.1 arc extinguishing copper gas in a one-time sealed, no need to run halfway inflation;

The annual leakage rate of 6.3.2 six sulfur fluoride gas is less than 0.1%;

6.3.3 mechanical life 10000 times, the performance is stable and reliable.

6.3.4 is especially suitable for the switched capacitor banks.

Five switch cabinet "7 anti" interlocking

7.1 to prevent load pull cart, the breaker handcart only in work, test or removed position can be done, closing operation. Circuit breaker is only in the closing position, the trolley can be from work position to remove or from the test position to promote, reliable prevent hand cart with load;

7.2 to prevent misuse, circuit breaker, grounding switch closing subsequent car rolled into the hole mechanism of valve unlock to the VCB truck from the test position is pushed into the working position; after the circuit breaker closing, shaking into institutions hole of the valve can not be opened, by mistake is prevented, misclassification error circuit breaker;

7.3 to prevent mistakenly charged spacing, switch cabinet after cabinet door adopts mechanical and electrical interlocking, only when the grounding switch is closed, and after cabinet corresponding devices have a power outage, open after the electromagnetic lock to open the door. Prevent the staff strayed into the charged interval;

When out of the switch cabinet handcart, static contact box outside the metal valve automatically shut down, to prevent contact with the contact box live parts and insulation (creepage) surface, to ensure safety.

7.4 prevent switch cabinet charged misconnecting earthed switch, only the truck pulled into the test position, and the outlet side also have a power outage, the grounding switch operating hole of the valve to open, allow off the grounding switch is closed;

7.5 prevented the grounding switch is closed when the miscarriage of the electricity, the earthing switch in the closed position, hand car beam on the grounding switch is connected locking rod can not be right toggle, handcart shaking mechanism hole valve is locked, the truck don't roll into and prevent when the grounding switch is closed and the miscarriage of the electricity.

7.6 does not install the grounding switch the circuit breaker cabinet and bus sectional cabinet and bus equipment cabinet, also need to be locked by the corresponding electromagnetic program (or lock) with the completion of all anti misoperation function, the user may reference KYN61-40.5 armoured removing type metal closed switch equipment interlock operating instructions for operation.
