Document Type and Number:
Japanese Patent JP6844702
Kind Code:
B2
Abstract:
A device protection apparatus comprising a first sensor for detecting temperature of a refrigerant used for cooling a device including a heat-generation part, a second sensor for detecting temperature of the device, and a controller 10 that applies drive limitation to the device based on a first detected temperature detected by the first sensor and a second detected temperature detected by the second sensor, wherein the controller 10 calculates a temperature difference between the first detected temperature and second detected temperature, applies drive limitation to the device when the temperature difference is higher than a predetermined temperature difference threshold value, and applies drive limitation to the device when the second detected temperature is higher than a predetermined first temperature threshold value.
