Introduction

KYN1-12kV metal armoring shift type AC switch cabinet is according to the national standard GB3906<3 ~ 35kV indoor AC metal closed switch device > in the highest level of metal clad type design, in line with the International Electrotechnical Commission IEC60298< rated voltages above 1kV and below 52kv AC metal closed switch equipment and Control Equipment > standard and meet the DL402, DL/T404 has "five anti" interlocking function. This product absorbs the advantages of similar products at home and abroad, compact structure, safe and reliable, convenient maintenance, performance is superior to other types of products.

Scope of application

This product is suitable for rated voltage is 3 ~ 10kV, 50Hz, rated current of 630 to 3150A three-phase AC single bus and single busbar segmentation system, as the acceptance and distribution of electric energy use. Can meet the needs of various types of power plants, substations and industrial and mining enterprises use requirements.

Model meaning

Structure characteristics

The structure of the product by the former cabinet after cabinet, relay control room, hand trolley and pressure relief device (upper cover) is composed of five parts. The former cabinet, after the cabinet and a pressure relief device is connected by bolts, relay instrument and front cabinet through the damper connection. The cabinet is divided into two parts: the handcart room and the two terminal room. After the cabinet is divided into two parts: the cable compartment and the main loop bus room. Each part of steel plate welded to import. Separated out cable, overhead line, or contact. Can be composed of complete sets of equipment distribution in the cabinet is very few, in order to meet the different requirements of the use of this product. According to the needs of a standard line bridge and two column cabinet connected across the bus bridge. Compared with the products of the same type of products with the following characteristics:

1. Safety a contact isolation valve, the truck in the movement between a position working position and import, the isolation valve automatically open or close, to ensure the safety of live overhaul.

2 there is sufficient electrical insulation strength. In the cabinet, the relative air distance is not less than 125mm.

3. With reliable mechanical interlock and satisfy the "five anti" requirements. Circuit breaker in the closing state can't push or draw out a hand car; circuit breaker only in brake state to lift the latch; hand car out of cabinet put oneself in another's position to close grounding switch; Switchgear running state can not open the door.

4. The main busbar adopts a "goods" - shaped layout, vertical installation, reducing the short circuit when the effects of electrical power. Current transformer and a contact integration, reducing the fault links, increase the space in the cabinet.

5 the operation is simple and convenient, with worm gear and worm propulsion mechanism.

6 with long life of the vacuum arc extinguishing chamber, operating mechanism, so that the maintenance workload greatly reduced.

The 7 level of protection to IP2X.
