KYN28A-12Type(GZS1)Indoor metal armored center-mounted removable switchgear (hereinafter referred to as switchgear) is a three-phase AC

50HZof indoor complete distribution units for receiving and distributing3-12KVThe network power and the circuit control protection and monitoring. Various types of microcomputer integrated relay protection devices can be installed on the panel of the relay chamber of this product, and can realize the intelligent control of the system, with remote control, telemetry, remote communication and remote adjustment functions, through the communication interfaceCANThe bus controls the field network and has the functions of preventing misoperation of the circuit breaker, preventing the load push-pull handcart, preventing the electrified closing of the grounding switch, preventing the grounding switch from transmitting electricity at the grounding position and preventing the accidental entry of the electrified interval, I .e. the "five-prevention" function for short. The cabinet can be usedVS1(I. e.ZN63）、ZN12KVVacuum circuit breaker, can also be configured with importedVD4Vacuum circuit breaker andVCSeries Vacuum Contactors.

Condensation may occur when the temperature drops sharply, accompanied by contamination This product is suitable for the following two environmental conditions that are more severe than normal:

Infrequent condensation (no more than twice a month on average) with mild contamination;

Generally, there is no condensation (no more than twice a year on average) with serious pollution;

4There is no fire, explosion hazard and serious pollution enough to corrode metal and damage insulation gas and other bad places;

No violent vibration, fatigue and vertical inclination not exceeding8° of the place.

Note:1.Permitted in-30When storage and transportation.

2.When the altitude exceeds1000marea,JB/Z102"Technical requirements for the use of high-voltage electrical appliances in altitude areas", when the altitude does not exceed2000mThe low-voltage auxiliary equipment does not need to take any measures.

3.When the actual use conditions are different from the above, the user and the manufacturer shall negotiate.

Product structure characteristics

The switch cabinet is composed of a fixed cabinet body and a withdrawable part (handcart). The cabinet shell and the partitions of each functional unit are bolted with aluminum-zinc steel plates. The enclosure protection level of the switch cabinet is upIP4XThe protection level of each compartment isIP2X. The switch cabinet has the functions of overhead incoming and outgoing lines, cable incoming and outgoing lines and left and right contact, and the switch cabinets of each scheme can be arranged according to the purpose to form a power distribution device that can complete the design function. The installation and commissioning of the switchgear can be carried out on the front, can be against the wall, in order to save floor space, reduce investment.
