(Summary description)The manufacturer of transformer 12kV swtichgear tells you that the switchgear is composed of various functional circuits (including grounding switchgear and load switchgear). The metal shell and the circuit are sealed with bus bars, and the shell is welded with 3mm cold-rolled steel plate (or stainless steel plate).

The manufacturer of transformer 12kV swtichgear tells you that the switchgear is composed of various functional circuits (including grounding switchgear and load switchgear). The metal shell and the circuit are sealed with bus bars, and the shell is welded with 3mm cold-rolled steel plate (or stainless steel plate). Each functional circuit includes a load switch and a ground switch. The load switch consists of a moving contact system that moves vertically and a static contact at the bottom. When the switch is closed, the moving contact moves down and the load switch opens.
The grounding switch consists of movable blades and fixed blades. When the spring moves, the grounding switch opens quickly. The transformer 12kV swtichgear manufacturer tells you that there are four rectangular assembly process holes on the top and back of the switch chamber. There is an observation window on the front of the ring network cabinet. You can see the "open" and "closed" positions of the grounding switch. An explosion-proof device is installed on the back of the ring body.
The load switch adopts the compressed air internal blowing structure. The arc extinguishing ability is strong, without affecting the phase-to-phase and ground insulation, and the moving and static contacts are equipped with arc contacts, which greatly increases the number of breaking times.
The transformer 12kV swtichgear manufacturer tells you that the next step is the fuse room, and the fuse and the load switch room constitute the transformer protection circuit. The high-voltage current-limiting fuse is installed in an epoxy resin casting insulating shell. After the fuse is blown, the striker pops up and the load switch is disconnected.
The control room is located at the front of the annulus. In each functional circuit, the load switch is equipped with a human (or electric) stored energy spring actuation mechanism. The transformer 12kV swtichgear manufacturer tells you that the grounding switch is equipped with a human body energy storage spring actuation mechanism, and there are opening and closing drive holes on the panel, which are used for the closing of the load switch, the manual opening knob and the grounding switch. Equipped with load switch opening and closing position indicator light and electric opening and closing button, analog line, switch status display board and locking position, the operation of load switch and grounding switch has interlocking to prevent misoperation.
