The invention relates to electrical equipment and a water receiving box thereof. The electrical equipment comprises a shell, wherein a condensation plate is arranged at the top of the shell and inclines, a receiving structure is arranged at a position, at a relatively low side of the condensation plate, of the shell and is used for receiving condensation water, a water outlet is formed in a side wall of the shell and is corresponding to the receiving structure, the water receiving box is arranged at an outer side of the side wall of the shell and comprises a box body, the bottom of the box body is enclosed, a water inlet is arranged in the box body and communicates with the water outlet of the shell, an accommodating space is arranged at the bottom of the box body and is used for collecting the condensation water, and a net-shaped ventilation hole is formed in the top of the box body and is used for preventing a foreign matter which does not conform to the corresponding protection class from entering. With the arrangement of the net-shaped ventilation hole, the protection class of the electrical equipment is ensured as well as the condensation water is evaporated out of the water receiving box, and the problem of a protection failure risk of a condensation-prevention device of the electrical equipment in the prior art is solved.
Description
technical field [0001] The invention relates to an electric device and a water receiving box thereof. Background technique [0002] In high-altitude or hot and humid areas, it is not uncommon to see condensation inside the distribution network switchgear due to factors such as large temperature differences. Condensation will reduce the insulation performance of the equipment, create conditions for flashover or creepage, and directly lead to operational failures. In the secondary system, condensation can be generated directly on micro switches and other similar components and secondary terminals, or condensation can fall from the top of the cabinet and combine with dust to cause short circuit (grounding) of AC and DC circuits, secondary short circuit, etc. Fault. In addition, condensation can cause corrosion of metal parts installed in the metal shell and reduce the operating life of equipment. Therefore, it is urgent to solve the problem of condensation in distribution netw...
