Ventilation and heat dissipation structure of active electric power metering box

Abstract

The invention discloses a ventilation and heat dissipation structure of an active electric power metering box. The structure comprises a box body, a box door is arranged on the box body, a plurality of groups of ventilation holes are formed in the box door, and a connecting pin is arranged on the box door. A fixed seat is arranged at the joint of the box body and the box door, and a fixed pin is arranged on the fixed seat; a supporting plate is arranged on one side of the box body, a supporting seat is arranged on the supporting plate, a motor is arranged on the supporting seat, a rotating shaft is arranged on the motor, and ventilation fan blades are arranged on the rotating shaft; an exhaust box is arranged on the other side of the box body, and an adjusting mechanism is arranged in theexhaust box. An installation hole is formed in the box body, and a dustproof net is arranged in the installation hole. The ventilation holes are formed, the structure is simple, use is convenient, andthe ventilation and heat dissipation effects are improved; ventilation fan blades are arranged, and the ventilation fan blades rotate to discharge heat generated in the box body; the adjusting mechanism is arranged, the adjusting mechanism closes the exhaust box in rainy seasons, rainwater is prevented from entering, and the waterproof performance is improved; a dust screen is arranged, so that alarge amount of dust is prevented from entering the box body, and the ventilation effect is reduced.

Description

technical field [0001] The invention belongs to the field of metering equipment, and relates to a metering box, in particular to an active power metering box ventilation and heat dissipation structure. Background technique [0002] Power metering box is a device used for electric energy metering in 3~35kv, including combined transformer (collecting three-phase current and voltage signals), box body, watt-hour meter, lightning arrester, vacuum circuit breaker (prepaid type), etc. ;Because there are multiple electrical equipment installed in the electric energy metering box, the electrical equipment will generate heat when it is working, especially in summer, no matter indoors or outdoors, the inside of the electric energy metering box is in a closed state, and the large amount of heat generated by the electrical equipment after working for a long time makes the The temperature in the electric energy metering box rises suddenly. If the heat is not dissipated in time, it will e...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an active ventilation and heat dissipation structure of the electric power metering box to solve the problem that in the prior art, the inside of the electric energy metering box is in a closed state, and the large amount of heat generated after the electrical equipment works for a long time makes the electric energy metering The temperature in the box rises suddenly, which may easily cause the components to burn out or even cause a fire, which is harmful to people's personal safety and property safety. Low efficiency, the traditional power metering box has complex structure, inconvenient use, no heat dissipation effect, and when the rainy season comes, rainwater is easy to corrode the power metering box, poor waterproof performance, and low practicability technical problems
