Embodiment approach

[0045] As an embodiment of the present invention, a sealing disk 3 is fixed inside the rotating conduit 23, and an air guide hole 31 is opened at a non-center position of the sealing disk 3; And the non-center position of the fitting disk 4 is provided with an exhaust groove 41; the fitting disk 4 and the sealing disk 3 are rotated and fitted; the exhaust groove 41 is rotated and aligned with the air guide hole 31; during work, when the rotating column 22 drives the fan blade plate 21 to rotate to the vertical state, and at this time the fan blade plate 21 will drive the rotating guide tube 23 to rotate, so that the air guide hole 31 on the inner sealing disc 3 of the rotating guide tube 23 and the end of the air guide tube 24 fit on the disc 4 The exhaust grooves 41 are aligned, and then the cooling gas in the air duct 24 will enter the cooling chamber 211 through the air guide holes 31 and the exhaust grooves 41, and then the cooling chamber 211 can be cooled; when the fan bl...

Abstract

The invention belongs to the technical field of high-voltage power distribution cabinets, and particularly relates to a high-voltage power distribution cabinet safety protection method, which comprises the following steps that a high-voltage power distribution cabinet is installed in a to-be-used area according to an existing construction process; when a temperature sensor in the high-voltage power distribution cabinet detects that the temperature of external air flowing into the cabinet body is higher than the internal temperature of the cabinet body, a controller indirectly drives a plurality of fan blade plates to rotate and close, so that the cabinet body is sealed; cold air is intermittently supplied to multiple air guide pipes through an air supply pump, the cold air enters a coolingcavity to cool the fan blade plates, and then components in the sealed cabinet body are cooled; and an exhaust fan works to discharge the cold air in the cabinet body to the periphery of the outsideof the cabinet body, so that the cold air generated in the cabinet body circularly flows. According to the invention, the safe and stable heat dissipation effect in the cabinet body is effectively improved, and the safety protection effect on components in the power distribution cabinet can be achieved.

Description

technical field [0001] The invention belongs to the technical field of high-voltage power distribution cabinets, in particular to a safety protection method for high-voltage power distribution cabinets. Background technique [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, Disconnectors and grounding switches, high-voltage load switches, high-voltage automatic reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof power distribution devices, and high-voltage switchgears. The high-voltage switch manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry, and occupies a very important position in the entire power industr...
