High-voltage switch cabinet capable of preventing water accumulation

Abstract

The invention discloses a high-voltage switch cabinet capable of preventing water accumulation. The high-voltage switch cabinet comprises an electric cabinet, a protective structure, an adjusting structure and a water accumulation preventing structure, wherein the right end of an opening in the front surface of the electric cabinet is hinged to the right side of the rear surface of the cabinet door through a hinge; the protective structure is arranged in an inner cavity of the electric cabinet, and mounting plates are vertically and uniformly arranged in the inner cavity of the protective structure; the adjusting structure is arranged on the lower surface of the electric cabinet, a trapezoidal table is arranged on the lower surface of the adjusting structure, and a water level sensor is arranged at the left end of the front surface of the adjusting structure; the water accumulation preventing structure is arranged on the lower surface of the trapezoidal table. The high-voltage switch cabinet also comprises a PLC controller. The PLC controller is arranged on the front surface of the cabinet door, and the input end of the PLC controller is electrically connected with an external power source. According to the high-voltage switch cabinet capable of preventing water accumulation, the safety coefficient of the electric cabinet in the using process is improved, the requirement for multi-layer protection is met, the water accumulation prevention effect is achieved, and the water accumulation condition is avoided through the design of various kinds of water drainage and leakage.

[0002] High-voltage power distribution cabinets refer to electrical products that are used for on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption, with a voltage level of 3.6kV to 550kV, mainly including high-voltage circuit breakers, Isolation switch and grounding switch, high-voltage load switch, high-voltage automatic recloser and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear, etc. High-voltage switch manufacturing industry is an important component of power transmission and transformation equipment manufacturing industry The part occupies a very important position in the entire power industry. The distribution cabinet should meet the relevant requirements of the GB3906-1991 "3-35kV AC metal-enclosed switchgear" standard. It is composed of two parts: the cabinet and the circuit breaker. The cabinet is composed of Housing, electrical components, various mechanisms, secondary terminals and wiring, etc., the general high-voltage switchgear needs to prevent water accumulation, but the existing high-voltage switchgear anti-water accumulation, the safety factor during the use of the electric cabinet It is not high enough to meet the needs of multi-layer protection, cannot meet the needs of up and down adjustment, and cannot quickly leak rainwater, which will cause large areas of water accumulation, and the speed of water flow is not fast enough to prevent water accumulation Function, can not prevent rainwater accumulation, can not avoid the occurrence of water accumulation, can not play the role of blocking rainwater when it rains
