[0042] A snap protector fixing device 100, a heat preservation barrel 200, at least one heater 300, a temperature sensor 400 and a controller 500;

[0043] The sudden jump protector fixing device 100 includes a multi-channel detection circuit, and the detection circuit is connected to the controller 500;

[0044] The sudden jump protector fixing device 100 is equipped with a plurality of sudden jump protector fixing mechanisms 101, and one sudden jump protector fixing mechanism 101 is used to connect one sudden jump protector in series in a corresponding detection circuit;

[0045] The heater 300 and the temperature sensor 400 are disposed in the heat preservation barrel, and the heater 300 and the temperature sensor 400 are connected to the controller 500 respectively;

[0046] The sudden jump protector fixing device 100 is detachably connected to the heat preservation barrel 200.

[0047] In this embodiment, there is no limitation on the connection method between the sudden jump protector fixing device 100 and the heat preservation barrel 200. For example, the two can be connected by means of threads, snaps, etc.

[0048] In this embodiment, the structure of the sudden jump protector fixing mechanism 101 is not limited. The sudden jump protector fixing mechanism 101 is used to fix the sudden jump protector so that the sudden jump protector is electrically connected to the detection circuit. The sudden jump protector fixing mechanism 101 can be a spring connector, a bolt connector, etc.

[0049] In this embodiment, the controller 500 is configured to control the operation of the heater 300, record the measurement data of the temperature sensor 400, and record the on / off status of the detection circuit.

[0050] In this embodiment, the use and working mode of the device for detecting the sudden trip protector are as follows:

[0051] Fix the (to be detected) sudden jump protector on the sudden jump protector fixing mechanism 101, so that the sudden jump protector is electrically connected to the detection circuit;

[0052] The sudden jump protector fixing device 100 is installed on the heat preservation barrel 200, so that the sudden jump protector is placed inside the heat preservation barrel;

[0053] The controller 500 controls the heater 300 to start operation, and the heater 300 heats the inside of the heat preservation barrel 200;

[0054] The controller 500 obtains the on / off state of the detection circuit and the measured temperature of the temperature sensor 400. When the detection circuit is disconnected, the controller 500 records the number of the detection circuit and the current measured temperature.

[0055] The controller 500 and the controller 300 stop operating, and the temperature of the heat preservation barrel 200 decreases. When the detection circuit is turned on, the number of the detection circuit is recorded, and the current measured temperature is recorded.

[0056] Exemplarily, in this embodiment, when a detection circuit is disconnected, the corresponding measured temperature recorded is the action temperature corresponding to the sudden trip protector provided in the detection circuit;

[0057] When a detection circuit is turned on, the corresponding measured temperature recorded is the reset temperature corresponding to the sudden jump protector set in the detection circuit.

[0058] The present embodiment proposes a device for detecting a sudden jump protector, which includes a sudden jump protector fixing device, an insulation barrel, a heater, a temperature sensor and a controller, wherein the heater is arranged in the insulation barrel, and the heater is used to heat the insulation barrel so that the temperature in the insulation barrel reaches the temperature range for the sudden jump protector to be operated. The sudden jump protector fixing device is used to electrically connect the sudden jump protector to be detected in the detection circuit. When the sudden jump protector is operated or reset, the detection circuit is disconnected or connected, and the controller records the on-off state of the detection circuit and the temperature in the insulation barrel when the on-off state of the detection circuit changes, and then the operating temperature or reset temperature of the sudden jump protector can be determined (manually or automatically). Based on the sudden jump protector fixing device and the detection circuit, the device can simultaneously install multiple sudden jump protectors to be detected, thereby improving the detection efficiency. At the same time, the operating temperature and reset temperature of the sudden jump protector are determined based on the on-off state of the detection circuit. Since the corresponding operating temperature and reset temperature are directly determined by the action of the sudden jump protector, the stability and accuracy of the detection are relatively high.

When the external storage device is connected to the controller, the data in the controller (the on / off status of the detection circuit, the corresponding test temperature, etc.) can be exported to the external storage device.

[0082] Based on the solution that the aforementioned device includes an operating table, in one possible implementation scheme, the device also includes a display screen;
