Equipment for detecting ptc heater and its detection method

Abstract

The invention discloses a device used for detecting a PTC (Positive Temperature Coefficient) heater and a detection method. The device comprises an oil hydraulic press, a fixture, a first driving member, a cold water machine and an electric control cabinet, and is characterized in that the oil hydraulic press is provided with a workbench, the fixture comprises a lower fixture and an upper fixture, the lower fixture is arranged on the workbench of the oil hydraulic press and relatively fixed with the oil hydraulic press, the upper fixture is arranged on the oil hydraulic press in a mode of being capable of moving between a clamping position and a releasing position, the upper fixture is buckled with the lower fixture at the clamping position so as to define an accommodating cavity, the upper fixture is provided with a probe and a temperature detection component, and the probe is suitable for being electrically connected with the PTC heater when the upper fixture is at the clamping position; the first driving member is arranged on the oil hydraulic press and is connected with the upper fixture; the cold water machine is connected with the fixture and used for being connected with the accommodating cavity in series when the upper fixture stays at the clamping position so as to enable water to pass; and the electric control cabinet is connected with the oil hydraulic press, the probe and the temperature detection component. The device used for detecting the PTC heater can improve the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of electric appliance detection, in particular to a device for detecting a PTC heater and a detection method thereof. Background technique [0002] There are some deficiencies in the detection scheme of the related art: first, the PTC (wherein, PTC is the abbreviation of PositiveTemperature Coefficient, and Chinese is positive temperature coefficient) heater requires manual clamping and disassembly, which is time-consuming, laborious and costly; second, the operation It is dangerous for personnel to directly operate the high-voltage power supply. If the operator forgets to turn on the coolant during the test and directly turns on the high voltage, or turns off the coolant first and then turns off the high voltage after the test, it will cause dry burning, burn out the plastic shell, and even cause a fire; , The peak current generally appears about 2 seconds after the power is turned on, and the change is ve...

Problems solved by technology

[0002] There are some deficiencies in the detection scheme of the related art: one, the PTC (wherein, PTC is the abbreviation of PositiveTemperature Coefficient, Chinese is the positive temperature coefficient) heater needs manual clamping and disassembly, time-consuming and laborious, and the cost is higher; It is dangerous for personnel to directly operate high-voltage power supply

If the operator forgets to turn on the coolant during the test and directly turns on the high voltage, or turns off the coolant first and then turns off the high voltage after the test, it will cause dry burning, burn out the plastic shell, and even cause a fire; , the peak current generally appears about 2 seconds after the power is turned on, and the change is very fast, and it is difficult to accurately obtain it with the naked eye; Fourth, the temperature of the coolant is not easy to control
