Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to a circuit maintenance current warning device. Background Art

[0002] Electricity is a natural phenomenon, referring to the physical phenomenon produced by static or moving electric charges. It is a property of the repulsive and attractive forces between subatomic particles such as electrons and protons. Lightning in nature is an electrical phenomenon. Electromagnetic force and counter-attraction are one of the four basic interactions in nature. There are two types of electron movement phenomena: atoms lacking electrons are called positively charged, and atoms with extra electrons are called negatively charged. Electricity has developed modern power industry and electronic technology. In real life, the mechanism of electricity gives many well-known effects, such as lightning, friction electrification, electrostatic induction, electromagnetic induction, etc. People use it to make electric lights glow, drive machinery to rotate, etc.

[0003] After searching, the utility model with publication number CN216848901U in the prior art discloses a UHV near-electric warning device, including a near-electric warning circuit installed in a housing, a piezoelectric buzzer, an external antenna, a band switch and a button battery; the warning chip is connected with the band switch and the gear selection resistor group to select the sensing gear; the warning chip, the external antenna and the input resistor form a sensing circuit to form the sensing voltage of the gear selected by the band switch; the warning chip, the filter resistor and the filter capacitor form a detection circuit to amplify and filter the induced voltage to generate a detection voltage, and compare and detect the detection voltage with the reference voltage of the warning chip itself; the warning chip, the triode, the sensor and the piezoelectric buzzer form an alarm circuit to sound an alarm. The near-electric warning circuit is designed, and when the maintenance personnel enter the unsafe distance of the high voltage and UHV electric field, the circuit can be used for sensing, detection and alarm, providing safety protection for the maintenance personnel. This method uses the pressure of environmental voltage to issue an alarm to alert workers of danger, thereby avoiding accidents. However, I believe that the above method has the disadvantage of a small range of use. The device needs to be held by workers or used close to the body, so the detection range is near the human body, which is not conducive to timely response by workers. Utility Model Content

[0022] In this embodiment, the device senses the voltage in the same manner as CN216848901U, and a lamp holder 3 and an alarm light 4 are provided on one side of the shell 1. When the voltage is too high, the central controller sends a signal to the alarm light 4, and the alarm light 4 flashes to warn the staff. At the same time, it can avoid the situation where the staff finds it difficult to distinguish the alarm of the buzzer 2 when the environment is noisy, resulting in the inability to evacuate the high-voltage area in time. When the device is in use, firstly, one end of the shell 1 is clamped into the inner cavity of the card slot 6, and then the connection between the card frame 5 and the shell 1 is locked by the first bolt 8. Then the staff can hold the handle 14 to drive the device to move, thereby expanding the detection range of the equipment and prolonging the reaction time of the staff in a sudden high-voltage environment.

[0023] Among them, a telescopic groove 11 is opened at one end of the sleeve rod 10, and the connecting rod 9 moves in the inner cavity of the telescopic groove 11.
