KYN28A-12 Armored Central AC Metal-enclosed Switchgear

KYN28A-12 Armored Central AC Metal-enclosed Switchgear

KYN28A-12 armored central AC metal-enclosed switchgear (hereinafter referred to as switchgear) is a new product designed and developed by Baixing based on the absorption of advanced manufacturing technology at home and abroad. It can replace all kinds of old metal-enclosed switchgear. Such as KYN1-12, JYN2- -12 and other products.Its products have the following distinct advantages:

KYN28A- 12 armored centrally-mounted metal-enclosed switchgear is suitable for 3.6--12KV three-phase AC 50Hz power grid, as a means of receiving and distributing electrical energy, and controlling, monitoring and protecting the circuit. Can be used for single busbars, single busbar segmentation systems or dual busbar systems. The switchgear complies with IEC298 "AC metal-enclosed switchgear and control equipment with rated voltage above 1 KV and below 52KV", IEC694 "Common Terms of High-Voltage Switch and Control Equipment", China GB3906 "3--36KV AC Metal-Enclosed Switchgear" and DIA04 "Order AC high voltage switchgear ordering conditions", Germany DIN.VDE0670 "AC switchgear with rated voltage above 1 KV" and other standards. And has a complete and reliable anti-misoperation function.

Model and its meaning

Normal use condition

When the conditions of use exceed the above range, the user should negotiate with our company to determine the allowable range and technical measures.

Note:

1 The electric heater should be turned on when the relative humidity is greater than 70%.

2 Where the altitude is more than 1000m, it shall be treated according to JB/Z102-71.

Mechanical characteristics of VD4 and VS1-12 vacuum circuit breakers

When the circuit breaker is used to control a 3 - 10kV motor, if the starting current is less than 600A, a metal zinc oxide arrester must be added. The specific requirements are negotiated by the user and our company; when the circuit breaker is used to open the capacitor bank, the rated current of the capacitor bank is not It should be greater than 80% of the rated current of the circuit breaker.Main technical parameters of ZN port-12 (VH1) vacuum circuit breaker

Use and description

Although the switchgear is designed to ensure the correct interlocking of the operating procedures of the various parts of the switchgear, the push and exit of the various parts of the switchgear by the operator should be carried out strictly in accordance with the operating procedures and the requirements of this technical document, and should not be operated at will. It should not be forced to operate without analysis when the operation is blocked. Otherwise, it may cause equipment damage or even cause an accident.

1 1.1 Operation of circuit breaker cabinet without grounding switch

Pay attention to the following during the switching process:

a hand cabinet operation

When preparing to push the handcart into the working position, in addition to complying with the requirements of b in 1.1.1, it should also be confirmed whether the grounding switch is in the open state, otherwise the next operation cannot be completed.

To make the grounding switch, first make sure that the handcart has been retracted to the test, 8 off position, and remove the pusher handle, then press the interlocking plate at the grounding switch operating hole, insert the grounding switch operating handle, turn clockwise At 90 degrees, the grounding switch is in the closed state. If you turn 90 degrees counterclockwise, the grounding switch will be opened.

The isolated handcart does not have the ability to press and disconnect the load current, so it is not allowed to pull the handcart under load. When operating in an isolated hand truck cabinet, it must be ensured that the circuit breaker that matches it is first opened (see 1 1 1 d), and the auxiliary contact switch is released and the handrail is isolated on the handrail after the circuit breaker is opened. The electrical interlock is the only way to operate the isolated car. The specific operating procedures are the same as those for operating the circuit breaker.
