Automatic cooling switch cabinet used for fuse type isolation switch

Abstract

The invention discloses an automatic cooling switch cabinet used for a fuse type isolation switch, belonging to the power system protection electric appliance technology field. The automatic cooling switch cabinet comprises a cabinet body, a fuse type isolation switch, a temperature-humidity detection unit, a control unit, an alarm unit and a fan. An air inlet and an air outlet are arranged on the cabinet; the fan is installed at the air inlet; the fuse type isolation switch is installed between the fan and the air inlet; the temperature-humidity detection unit is connected to the control unit for detecting temperature and humidity inside the cabinet body; and the output terminal of the control unit is connected to the alarm unit and the fan. With the air inlet and the air outlet being arranged on the switch cabinet, the automatic cooling switch cabinet performs real-time monitoring on the temperature inside the switch cabinet and starts up the fan to radiate heat when the temperature and the humidity are detected to be high, which solves the problem that the temperature inside the switch cabinet is too high, which affects the working of the fuse type isolation switch. Besides, the invention also has advantages of automatic heat radiation, autonomous detection, easy usage and low cost.

Description

technical field [0001] The invention belongs to the technical field of electrical system protection appliances, relates to the direction of a fuse-type isolating switch, and in particular relates to an automatic cooling switch cabinet for a fuse-type isolating switch. Background technique [0002] At present, the RC1A outdoor porcelain plug-in fuse series products commonly used by low-voltage users are generally hung and installed in the open air next to the straight iron or flat-point iron plate. With the improvement of people's living standards and the increase in the number of residents' air conditioners, the electricity load of residents has increased sharply. The traditional fuses for inserting insurance cannot be firmly in place, and they are easy to loosen and generate heat, resulting in a high failure rate. According to the new fuse-type isolating switch designed by the user, the fuse adopts a stuffed fuse tube, which is fully sealed and waterproof, and is not affect...

AI Technical Summary

Problems solved by technology

[0003] According to the deficiencies of the prior art above, the technical problem to be solved by the present invention is to propose an automatic cooling switchgear for a fuse-type isolating switch, by setting an air inlet and an air outlet on the switchgear, and controlling the temperature Real-time detection turns on the fan to dissipate heat when the temperature and humidity are high, which solves the problem that the high temperature in the switchgear affects the work of the fuse-type isolating switch. It has the advantages of automatic heat dissipation, independent detection, simple use, and low cost
