Temperature monitoring device for main loop connector of direct-current switch cabinet

Abstract

The invention discloses a temperature monitoring device for a main loop connector of a direct-current switch cabinet. The device comprises a non-contact sensor, an environment temperature and humiditysensor, a temperature centralized processing module, a relay output module and an alarm display unit. The non-contact sensor is arranged beside a current-carrying conductor in the switch cabinet andis used for measuring the temperature of the current-carrying conductor; the environment temperature and humidity sensor is arranged in a small chamber in the switch cabinet and is used for measuringthe environment temperature and humidity in the small chamber; the non-contact sensor and the environment temperature and humidity sensor are both connected with the temperature centralized processingmodule so as to transmit measured data to the temperature centralized processing module. The temperature centralized processing module is connected with the relay output module and the alarm displayunit, and when the temperature and the humidity are abnormal, the alarm display unit gives an alarm and controls the fan or the heater to perform temperature and humidity reverse adjustment through the relay output module.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a temperature monitoring device for a main circuit connector of a DC switch cabinet. Background technique [0002] As a kind of electrical centralized facility, the switchgear contains many high and low voltage electrical components. In order to ensure the normal operation of the electrical components in the switchgear, it is necessary to maintain suitable environmental conditions inside the switchgear. Overheating can easily damage the insulation, and overcooling can easily cause Condensation will cause insulation to drop, and conductor overheating will cause oxidation or welding of contact parts. Therefore, it is necessary to monitor the environmental conditions in the switchgear in time. Contents of the invention [0003] The object of the present invention is to provide a temperature monitoring device for a main circuit connector of a DC switchgear to solve the problems ...
