Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, specifically to an electrical device with leakage current detection function. Background Technology

[0002] Electrical cabinets are made of steel and are used to protect components and ensure their proper functioning. They are generally made of hot-rolled steel plate or cold-rolled steel plate and are widely used in industries such as chemical, environmental protection, power systems, and fire safety monitoring. Currently, electrical cabinets on the market often have leakage problems, but there is a lack of corresponding devices to detect and handle these leaks. Furthermore, if leakage inside the electrical cabinet is not dealt with in a timely manner, it may lead to short circuits and open flames. Therefore, an electrical device with leakage detection function is needed to improve the situation. Summary of the Invention

[0003] The purpose of this invention is to provide an electrical device with leakage current detection function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An electrical device with leakage current detection function includes an electrical device body. Several terminals are fixedly installed inside the electrical device body. Power-connecting bolts are threaded onto the surfaces of the terminals. A leakage current sensor is correspondingly installed at the lower end of each terminal. An indicator light is installed on the surface of the leakage current sensor. A wire is connected to the power supply through the terminal and the power-connecting bolt, and then passes through the leakage current sensor. When the leakage current sensor is powered, the indicator light illuminates, indicating normal operation. A smoke sensor is fixedly installed at the upper end inside the electrical device body. A temperature sensor is installed on one side of the smoke sensor. A leakage current protection device (RCD) is fixedly installed on one side of the electrical device body. The RCD disconnects power to the wiring in case of leakage. A hinged door is installed on one side of the electrical device body. Several slide rails are fixedly installed on the inner surface of the switch door. A slider slides on the surface of the slide rails. A spray bar is fixedly installed on one side of the slider, and several spray nozzles are fixedly installed on the surface of the spray bar.

[0006] As a preferred embodiment of this utility model, a motor is fixedly mounted on the surface of the switch door, a lead screw is driven at the upper end of the motor, a nut is threadedly connected to the surface of the lead screw, and the nut is fixedly connected to the spray rod.

[0007] As a preferred embodiment of this utility model, a carbon dioxide fire extinguisher canister is provided at the lower end of the electrical device body. The carbon dioxide fire extinguisher canister is connected to the spray rod through a hose. An electromagnetic valve is connected in the middle of the hose. A smoke sensor can detect smoke. When there is smoke, the microcontroller processor controls the opening of the electromagnetic valve, and the carbon dioxide gas in the carbon dioxide fire extinguisher canister enters the spray rod and is sprayed out through the nozzle. The motor is started to drive the lead screw to rotate, thereby driving the nut to move up and down, indirectly driving the spray rod to slide up and down on the slide rail surface through the slider to spray and extinguish the fire.

[0008] As a preferred embodiment of this utility model, a microcontroller processor is provided at the lower end of the electrical device body. The input terminal of the microcontroller processor is electrically connected to a temperature sensor, a leakage current sensor, and a smoke sensor. The temperature sensor can sense the temperature inside the electrical compartment, and the microcontroller processor starts a cooling fan to cool the heat dissipation fins.

[0009] As a preferred embodiment of this utility model, the output terminal of the microcontroller is electrically connected to the motor, buzzer, display, cooling fan and solenoid valve. The induced current is displayed on the display. When leakage occurs and the current is abnormal, the microcontroller controls the buzzer to sound an alarm.

[0010] As a preferred embodiment of this utility model, the buzzer and the display are fixedly mounted on the outer surface of the electrical device body.

When the leakage current sensor is powered on, the indicator light illuminates, indicating normal operation. The induced current is displayed on the screen. When leakage occurs and the current is abnormal, the microcontroller processor controls the buzzer to sound an alarm, and at the same time, the leakage protection device cuts off the power to the wiring, ensuring timely detection and alarm of leakage faults.

[0014] In this invention, a temperature sensor can sense the temperature inside the electrical compartment, a microcontroller processor starts a cooling fan to cool the heat sink fins, a smoke sensor can sense smoke, and when there is smoke, the microcontroller processor controls the opening of a solenoid valve, allowing carbon dioxide gas from the carbon dioxide fire extinguisher canister to enter the spray bar and be sprayed out through the nozzle.
