[0002] A high-voltage power supply box is a special power supply device that can convert low voltage and high current input into high voltage and low current output. It is widely used in many fields such as industry, scientific research, medical treatment and environmental protection. High-voltage power supply box detection is an important part to ensure its safe and reliable operation, including appearance inspection, insulation inspection, wiring inspection, electrical parameter testing and mechanical status inspection. Existing high-voltage power supply boxes are usually prone to leakage during detection, or improper use or mismatch of the detection device can easily cause the internal circuit temperature to be too high, resulting in circuit failure and low safety. Utility Model Content

[0003] In order to overcome the existing high-voltage power supply box, it is usually easy to cause leakage during detection, or the internal circuit temperature is easily too high due to improper use or mismatch of the detection device, resulting in circuit failure and low safety.

[0004] The technical solution of the utility model is: a protection device for detecting a high-voltage power supply box, comprising a box body, a grounding component, a first protection component, a second protection component, a heat dissipation component and a mounting module, a grounding component for protecting the safety of equipment and detection personnel in case of leakage is fixedly installed on the left lower end of the box body, a first protection component for detecting the magnitude of current and voltage is fixedly installed on the left end of the box body, a second protection component for detecting the temperature condition inside the box body is fixedly installed on the right end of the box body, a heat dissipation component for increasing heat dissipation is detachably installed on the middle upper end of the box body, and a mounting module for installing and fixing the box body is fixedly installed on the rear end of the box body.

[0005] Preferably, by setting a grounding component, when leakage occurs during the detection process, the leakage can be promptly introduced into the underground to prevent the leakage from causing harm to the staff or causing circuit failure. By setting a first protection component, it can be used to monitor the current and voltage conditions during the detection process of the power box. When the internal current and voltage are abnormal, the current and voltage tester will automatically cut off the internal circuit. By setting a second protection component, it can be used to detect the temperature conditions inside the box. By setting a heat dissipation component, heat dissipation can be promoted when the power box is detected. Under the multiple protection effects of the grounding component, the first protection component, the second protection component and the heat dissipation component, multi-angle protection can be performed during the detection of the power box, thereby making it safer and ensuring both the normal operation of the power box and the safety of the staff.

[0006] Preferably, the grounding assembly includes a baffle, a rotating shaft, a grounding wire, a driving motor and a grounding body. Two groups of baffles are arranged opposite to each other. A rotating shaft for rotation is provided between the two groups of baffles. The outer side of the rotating shaft is wound with a grounding wire for introducing leakage current generated during the detection process into the grounding body. One end of the grounding wire away from the box is fixedly connected to a grounding body for introducing leakage current into the underground. The grounding wire is electrically connected to the internal structure of the box. By setting the grounding wire, the leakage current can be guided so that the leakage current is introduced into the underground through the grounding body, thereby preventing the leakage current from causing harm to the staff or causing circuit failure.

[0007] Preferably, the drive motor is provided with an output shaft, which passes through the outer side of the lower baffle and extends to the inner driving shaft to rotate. By setting the drive motor to drive the shaft to reel in the grounding wire, the length of the grounding wire can be adjusted according to actual conditions to avoid safety accidents caused by cluttered grounding wires.

[0008] Preferably, the first protection component includes a current and voltage tester, a mounting block, a speaker and an alarm light. The upper end of the current and voltage tester is electrically connected to a mounting block for mounting the speaker and the alarm light. The upper end of the mounting block is fixedly mounted with an alarm light for warning. The front end of the mounting block is fixedly mounted with a speaker for voice warning. The speaker and the alarm light are electrically connected to the current and voltage tester through the mounting block. The current and voltage tester is electrically connected to the internal structure of the box. The alarm light is set to flash for warning, and the speaker synchronously gives voice warnings, so that the staff can find the problem in time and deal with it to avoid internal circuit failure.

[0009] Preferably, the second protection component includes a temperature detector, a temperature sensor and a connecting line. The rear end of the temperature detector is electrically connected to a temperature sensor for detecting the internal temperature of the box. The temperature sensor extends through the outside of the box to the inside. The temperature detector is electrically connected to the internal structure of the box through the connecting line. By arranging a temperature sensor to sense the temperature changes inside the box, the temperature detector can be used to control the automatic power cut-off when it is detected that the internal temperature of the box is too high, thereby avoiding circuit damage caused by excessive temperature.

[0010] Preferably, the heat dissipation assembly includes a fan, a heat dissipation box, a fixed frame, mounting holes and heat dissipation holes. The fan is embedded and installed in the upper end of the box. The upper end of the fan is provided with a heat dissipation box for preventing dust from entering the box. The lower end side of the heat dissipation box is fixedly connected to a fixing frame for connecting to the box. The upper four corners of the fixed frame are surrounded by mounting holes for detachable connection with the box. By setting up the heat dissipation box, external dust can be prevented from entering the box through the fan.

[0011] Preferably, multiple groups of heat dissipation holes are evenly distributed linearly on the upper parts of the left and right ends of the heat dissipation box. The fan draws the hot air in the box into the heat dissipation box so that the hot air is dissipated from the heat dissipation holes on the heat dissipation box.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional high-voltage power supply box, it is usually easy to cause leakage during detection, or the internal circuit temperature is easily too high due to improper use or mismatch of the detection device, resulting in circuit failure, and the safety is low. By setting the grounding component, when leakage occurs during the detection process, the leakage can be introduced into the ground in time to avoid leakage causing harm to the staff or circuit failure. The grounding wire can be used to guide the leakage. By setting a grounding body for inserting into the ground, the leakage guided by the grounding wire can be introduced into the ground. By setting the driving motor, the rotating shaft can be driven to rotate to reel the grounding wire, so that the length of the grounding wire can be adjusted according to the actual situation to avoid safety accidents caused by the messy grounding wire. By setting the first protection component, it can be used to monitor the current and voltage conditions during the power box detection process. When the internal current and voltage are abnormal, the current and voltage tester will automatically cut off the internal circuit, and start the speaker and alarm light to work. The alarm light flashes for warning, and the speaker simultaneously gives a voice warning reminder, so that the staff can find the problem in time and deal with it to avoid internal circuit failure.

[0014] 2. By setting up a second protection component, it can be used to detect the temperature condition inside the box. By setting up a temperature sensor, it can be used to sense the temperature change inside the box. By setting the temperature detector to be electrically connected with the internal structure, when the temperature sensor detects that the temperature inside the box is too high, the temperature detector will automatically cut off the power supply to avoid circuit damage caused by excessive temperature. By setting up a heat dissipation component, heat dissipation can be promoted when the power box is tested. By setting up a fan, the hot air inside the box can be sucked into the heat dissipation box, which can prevent the heat from accumulating inside the box and causing the temperature to rise. By setting up a heat dissipation box, external dust can be prevented from entering the box through the fan. By opening heat dissipation holes on the heat dissipation box, the hot air in the heat dissipation box can be discharged to the outside, thereby playing a role in heat dissipation.
