[0002] When measuring high-voltage insulation, it is usually necessary to wear insulating gloves and then hold the probe of an electrician's pen or a megohmmeter for detection.

[0003] However, when an electrician is performing high-voltage insulation measurement, forgetting to wear insulating gloves or being unwilling to wear insulating gloves poses a safety hazard of electric shock to the electrician's measurement work. Summary of the Invention

[0004] In order to solve the technical problems in the prior art that when an electrician is performing high-voltage insulation measurement, forgetting to wear insulating gloves or being unwilling to wear insulating gloves poses a safety hazard of electric shock to the electrician's measurement work, the present invention provides an insulating glove monitoring device, an electrician's pen and a megohmmeter applied to an electrician's pen.

[0007] The beneficial effects of the present invention are as follows: When an electrician picks up an electric pen for insulation detection without wearing insulating gloves and holds the handle of the electric pen with one hand, when the first conductive block and the second conductive block are in contact with the skin of one hand, the first conductive block and the second conductive block are conducted. The high-level voltage connected to the first conductive block is transmitted to the input end of the inverter through the second conductive block. After inversion by the inverter, a low-level voltage is output. The control end of the switch module is connected to the low-level voltage, the switch module is disconnected, and the display module stops power supply, so the display module cannot display the test result of the electric pen. When an electrician wears insulating gloves and picks up the electric pen for insulation detection and holds the handle of the electric pen with one hand, when the first conductive block and the second conductive block are in contact through the insulating gloves, the first conductive block and the second conductive block are disconnected, and no voltage is connected to the second conductive block. Therefore, the input end of the inverter is in a low-level voltage state. After inversion by the inverter, a high-level voltage is output. The control end of the switch module is connected to this high-level voltage, the switch module is turned on, the display module is connected to the power supply voltage, and the power supply to the display module is realized, and the display module displays the test result of the electric pen. The present invention can improve the safety of electricians when using an electric pen to measure high-voltage insulation.

The first conductive block 1 and the second conductive block 2 are adjacently arranged on the handle 9 of the electrician's pen, and the first conductive block 1 is connected to a high-level voltage. The second conductive block 2 is connected to the input end of the inverter 5, the output end of the inverter 5 is connected to the control end of the switch module 7, one end of the switch module 7 is connected to the power supply voltage, and the other end of the switch module 7 is connected to the display module 8. The input end of the signal amplifier 6 is connected to the output end of the inverter 5, and the output end of the signal amplifier 6 is connected to the control end of the switch module 7. The switch module 7 is a high-level trigger switch.

[0035] When an electrician picks up an electric pen for insulation detection without wearing insulating gloves and holds the handle 9 of the electric pen with one hand, when the first conductive block 1 and the second conductive block 2 are in contact with the skin of one hand, the first conductive block 1 and the second conductive block 2 are conducted. The high-level voltage connected to the first conductive block 1 is transmitted to the input end of the inverter 5 through the second conductive block 2. After the inverter 5 performs inversion, a low-level voltage is output. The control end of the switch module 7 is connected to the low-level voltage, the switch module 7 is disconnected, the display module 8 stops power supply, and the display module 8 cannot display the test result of the electric pen; when an electrician wears insulating gloves and picks up the electric pen for insulation detection and holds the handle 9 of the electric pen with one hand, when the first conductive block 1 and the second conductive block 2 are in contact through the insulating gloves, the first conductive block 1 and the second conductive block 2 are disconnected, and no voltage is connected to the second conductive block 2. Therefore, the input end of the inverter 5 is in a low-level voltage state. After the inverter 5 performs inversion, a high-level voltage is output.
