Abstract

The invention provides a temperature protection device for a filter capacitor bank. The capacitor bank comprises two or more capacitors which are arranged in an array manner. The temperature protection device is characterized in that the temperature protection device comprises a temperature measurement device which comprises a cover body covering the capacitor bank; a single temperature sensor fixed on the central area of the cover body and used for measuring the temperature value of the capacitor bank; and a heat conduction pad positioned between the cover body and the capacitor bank, whereinthe heat conduction pad and the cover body are matched in shape. According to the temperature protection device, the cost is saved, and temperature protection can be accurately carried out on the capacitor bank.

Description

technical field [0001] The invention relates to a temperature protection device, in particular to a temperature protection device for a filter capacitor bank. Background technique [0002] In the circuit in the prior art, there may be a capacitor bank formed by parallel connection of multiple capacitors, for example, to filter the high-frequency ripple current that may exist in the circuit. The capacitor bank will filter the high-frequency ripple current in the process of filtering Heat is generated, and individual capacitors in the capacitor bank are prone to failure, which in turn can damage the entire capacitor bank or other parts of the circuit. Therefore, it is necessary to detect the temperature of the capacitor bank in real time. [0003] On the other hand, the existing temperature protection device includes a plurality of temperature measuring devices, each of which is used to measure the temperature of a corresponding capacitor to perform temperature protection on ...
