Description
Technical Field
The utility model belongs to the technical field of electrical equipment, concretely relates to resistance cabinet top cap structure.
Background
The resistance cabinet, generator neutral point high resistance ground connection to limit ground current, prevent the harm of various overvoltage. The neutral point can limit the fault current to a proper value through grounding of the resistor, the sensitivity of relay protection is improved to act on tripping, meanwhile, the fault point is only possible to be locally slightly burnt, the transient overvoltage is limited to 2.6 times of the voltage of the neutral point from the normal line voltage, the restriking of electric arcs is limited, the overvoltage of an arc light gap is prevented from damaging a main device, meanwhile, the ferromagnetic resonance overvoltage can be effectively prevented, and therefore the safe operation of the generator is guaranteed.
In a high-power circuit, a large amount of heat is generated in the power-on process of the high-power resistor cabinet, and the generated heat needs to be discharged in time, otherwise, potential safety hazards are generated.
Disclosure of Invention
To the problem that exists, the utility model aims at providing a resistance cabinet top cap structure with quick heat dissipation function.
In order to solve the technical problem, the utility model provides a scheme is: the top cover structure of the resistor cabinet comprises a top cover plate, wherein the top cover plate is installed on an upper side beam of a cabinet body of the electric cabinet, a fan cover is installed on the inner side of the top cover, a ventilation hole is formed in the fan cover, a fan is installed in the fan cover and fixed on a fan support, and the fan support is installed on the top cover plate.
The top cover of the cabinet body is fixed with the upper side beam of the frame of the cabinet body through bolts.
The fan cover and the top cover are connected through bolts and fixed on the upper side beam of the cabinet body.
The fan covers and is opened the ventilation hole and ventilation hole department welding has the screen cloth.
The fan is connected with the fan bracket and is fixed on the top cover through a bolt.
The utility model has the advantages that: the fan cover is arranged on the top cover, so that the fan can be maintained by directly disassembling the fan cover without opening the cabinet body; a large number of ventilation holes are formed in the fan cover, and a fan is arranged in the fan cover, so that heat dissipation is easy.
