Abstract
The present invention provides a temperature protective device for a filter capacitor bank. The capacitor bank comprises two or more capacitors which are arranged in an array manner. The temperature protective device comprises a temperature measurement device which comprises: a cover body covering the capacitor bank; a single temperature sensor fixed at a center area of the cover body, which is used for measuring a temperature value of the capacitor bank; and a heat conduction pad located between the cover body and the capacitor bank, wherein the heat conduction pad and the cover body have fitted shapes. The temperature protective device of the present invention saves cost and can accurately realize temperature protection of the capacitor bank.
