Compressor fan over-temperature protection tester

Abstract

The invention discloses an ultra-temperature protection tester of a forced draught fan. The ultra-temperature protection tester comprises a shell, wherein a toggle switch, a rough adjusting resistor, a fine adjusting resistor and a fuse tube are arranged inside the shell; a public wiring terminal of the toggle switch is serially connected with the rough adjusting resistor, the fine adjusting resistor and the fuse tube; one end of the toggle switch extends out of the shell through a lead and is connected with a rapid protection experiment plug; the other end of the toggle switch extends out of the shell through another lead and is connected with an internal rapid testing plug. By adopting the ultra-temperature protection tester of the forced draught fan, not only is the experiment process simplified, but also protection experiment can be performed in a power-on state of the forced draught fan, and the purpose of clearly and definitely verifying whether the temperature protection function of the forced draught fan is normal or not can be achieved.

Description

technical field [0001] The invention relates to a temperature protection test device, in particular to a pressure fan over-temperature protection tester. Background technique [0002] According to relevant national safety regulations, mining air compressors need to be tested for over-temperature protection, but because the temperature sensor is inside the compressor body, the traditional test method can only remove the temperature sensor in the shutdown state, and test the temperature sensor outside the compressor. Roasting with fire or immersing in oil and cooking with oil will increase the temperature, and then force the compressor to issue an over-temperature fault alarm. In this way, the protection test is cumbersome and difficult to test. At the same time, repeated disassembly will cause a large loss to the equipment itself. At the same time, because this method cannot be turned on for the test, it is impossible to truly verify whether the compressor can protect against...

[0002] According to relevant national safety regulations, mining air compressors need to be tested for over-temperature protection, but because the temperature sensor is inside the compressor body, the traditional test method can only remove the temperature sensor in the shutdown state, and test the temperature sensor outside the compressor. Roasting or immersing in oil and cooking with oil will increase the temperature, and then force the compressor to issue an over-temperature fault alarm

In this way, the protection test is cumbersome and difficult to test. At the same time, repeated disassembly will cause a large loss to the equipment itself. At the same time, because this method cannot be turned on for the test, it is impossible to truly verify whether the compressor can protect against tripping, shutdown, over-temperature Whether the protection function can achieve the effect, it cannot ensure whether the over-temperature protection function of the compressor works normally

It will cause difficulties to the over-temperature protection test, easily lead to misjudgment, and have potential safety hazards
