XGN66A-12 metal fixed switchgear

Overview
XGN66A-12 box type (indoor) AC metal-enclosed switchgear (hereinafter referred to as switchgear) meets the national standard GB3906 "3 ~ 35kV AC metal-enclosed switchgear" and the Ministry of Power DL404 "Indoor AC high-voltage switchgear ordering technical conditions" requirements It also meets the requirements of the international standard IEC298 "AC metal-enclosed switchgear and control equipment above 1kV and below 52kV", and has two "five-proof" blocking functions. The circuit breaker has high reliability and good performance, and the "five-proof" interlocking mechanism is reliable and simple.
Main use and scope of application
The switchgear is suitable for 3.6~12kV three-phase AC 50Hz single busbar segmentation indoor unit. It is used for receiving and distributing electric energy, and has the functions of controlling, protecting and monitoring the circuit. It can be applied to all types of power plants. Substations, industrial and mining enterprises, high-rise buildings and other places can also be combined with ring network cabinets for use in opening and closing.

product structure
The switch cabinet is a metal closed box structure as shown in Figure 2. The cabinet frame is assembled by bending the steel plate. The cabinet is divided into a circuit breaker room, a main bus room, a cable room, and a secondary component room.
The top of the switchgear is the busbar compartment, the front of the busbar compartment is the secondary component room, the middle of the cabinet is the circuit breaker compartment, and the isolation switch operation interlocking mechanism is arranged on the right side (or the left side), and the current transformer and illumination are installed on the rear side. The device, etc., the lower part of the cabinet is a cable room, and can be equipped with an arrester.
