The busbar room Pressure relief cover, switch chamber pressure relief cover, the front of the small bus chamber is provided with a brow, the top of the small bus chamber is provided with a small bus chamber cover, the cable chamber pressure relief cover , the left end of the pressure relief cover of the busbar chamber and the pressure relief cover of the switch chamber is provided with a first waterproof cover, and a first diversion groove is provided between the left end of the grid plate on one side and the first waterproof cover, so The right end of the grid plate on the other side is provided with a second diversion groove, the left end of each of the pressure relief cover plates is provided with a first drip eaves, and the right end is provided with a second drip eaves. A first waterproof eaves is provided at the joint of the gland plate and the pressure relief cover of the busbar room, and a second waterproof eave is provided at the joint of the pressure relief cover of the busbar room and the pressure relief cover of the switch room. The front end of the small busbar room A third dripping eaves is also provided, and waterproof mechanisms are provided on both sides of the small busbar room.

The rear end of the pressure relief cover plate of the cable room is provided with a fourth dripping eaves, and the fourth dripping eaves (both) are inclined downward at 5°-10° from the plane.

The waterproof mechanism includes a second waterproof cover arranged at the left end of the small bus chamber and connected with the small bus chamber cover.

The waterproof mechanism is also provided with a baffle, and the baffle is integrated with the small busbar chamber cover.

The cover plate of the small busbar chamber is fixed on the top of the small busbar chamber by bolts.

The pressure relief cover plate is fixed on the top of the pressure relief passage of the cable chamber, the pressure relief passage of the busbar chamber and the pressure relief passage of the switch chamber through bolts.

Waterproof rubber pads are installed on the bolts.

The first drip eaves, the second drip eaves and the third drip eaves are inclined downward at 5°-10° from the plane.

The first waterproof eaves and the second waterproof eaves extend upward and bend to form a certain angle, and the angle is less than 90° and greater than 0°.

In the above technical solution, since the left end of each pressure relief cover plate is provided with a first drip eaves, and the right end is provided with a second drip eaves, and the first and second drip eaves are both inclined downward at a certain angle to the plane, and at the same time, the grid plate A first diversion groove is arranged between the front end and the first waterproof cover, a first diversion groove is arranged between the left end of one grid plate and the first waterproof cover, and a first diversion groove is arranged at the right end of the other grid plate. The second diversion groove, so that the water flows along the dripping eaves into the first diversion groove and the second diversion groove, and when the water in the diversion groove accumulates to a certain extent, it will automatically flow to the ground without affecting the switch The cabinet is affected. The waterproof mechanism installed on the top of the small busbar room is the second waterproof cover connected to the small busbar room cover at the left end of the small busbar room, the baffle integrated with the small busbar room cover, and the front end of the small busbar room. The third dripping eaves are set, so that if there is water accumulation on the cover plate of the small busbar room, the accumulated water can drip directly from the third dripping eaves of the small busbar room due to the blocking of the second waterproof cover plate and the baffle plate to the ground, or the accumulated water flows from the first drip eaves to the first diversion trough through the pressure relief cover of the switch room, and then drips from the first diversion trough to the ground, or the accumulated water flows through the second drip eaves into the second diversion groove, and then drip from the second diversion groove to the ground, so that the water will not enter the switch cabinet and will not affect the normal operation of the switch cabinet. At the same time, the bolts are equipped with waterproof rubber pads , the accumulated water will not flow into the switchgear through the gap of the bolts, which will affect the work and safety of the switchgear. There are waterproof eaves at the joints between them, and the waterproof eaves extend upward and bend at a certain angle, which can prevent water from seeping into the switchgear from the joints.

The beneficial effect of the utility model lies in: preventing accumulated water from entering the switchgear and affecting the performance of the switchgear, high safety, making the protection level of the switchgear reach IP41, ensuring the pressure release, ventilation and heat dissipation of the switchgear, and having waterproof functions at the same time.
