[0002] Electrical distribution equipment is an indispensable and important component of the power system, widely used in various power consumption locations. With the growth of electricity demand and the increasing demands for electrical safety, traditional distribution equipment faces challenges in terms of safety, reliability, and intelligence. In recent years, various improved distribution equipment has emerged on the market, such as those employing modular design and intelligent monitoring technologies; however, the stability and fault protection capabilities of these devices in extreme environments still need improvement.

[0003] Regarding the aforementioned technologies, the inventors have discovered that with the increase and clustering of various circuit modules inside power distribution equipment, electric arcs are easily generated inside the power distribution equipment in extreme high temperature or high humidity environments, which can lead to safety accidents. Therefore, improvements are needed. Summary of the Invention

[0005] The high-safety complete set of electrical power distribution equipment provided in this application adopts the following technical solution: A high-safety electrical complete set of power distribution equipment includes a cabinet and a cabinet door rotatably mounted on the cabinet; a movable block is slidably mounted on the cabinet door, and an arc-extinguishing component for arc extinguishing is mounted on the movable block; the movable component on the cabinet door is used to move the arc-extinguishing component by the movable block; a detection component is mounted on the cabinet to detect environmental information inside the cabinet.

[0006] By adopting the above technical solution, the detection component monitors the environmental information inside the cabinet in real time, so as to remind workers of the internal status of the cabinet and thus facilitate timely prevention of safety accidents. Based on the information provided by the detection component, the moving component drives the moving block to move the arc extinguishing component to the location where the electric arc is generated. The arc extinguishing component performs arc extinguishing treatment, thereby reducing safety accidents caused by electric arcs inside the power distribution equipment and improving the safety of the power distribution equipment.

[0007] Preferably, the arc extinguishing assembly includes a jet nozzle, a gas storage cylinder, and a gas supply pipe; the jet nozzle is disposed on the movable block and faces the inside of the cabinet; the gas storage cylinder is disposed on the movable block for supplying compressed gas, and the gas supply pipe is connected between the jet nozzle and the gas storage cylinder.

[0008] By adopting the above technical solution, the gas storage cylinder and the gas supply pipe provide compressed gas to the jet nozzle, and the jet nozzle sprays a large amount of compressed gas toward the electric arc to cool and blow away the electric arc, thereby extinguishing the arc.

[0009] Preferably, the arc extinguishing assembly further includes a circulation pipe and a vent pipe; the circulation pipe is disposed on the side wall of the moving block facing the air nozzle, the circulation pipe covers the air nozzle, and the side wall of the circulation pipe facing the interior of the cabinet has an air nozzle; the vent pipe is connected between the circulation pipe and the air supply pipe.

[0010] By adopting the above technical solution, the ventilation pipe is connected to the air supply pipe to supply air to the inside of the circulation pipe, and a cylindrical air curtain is emitted through the jet nozzle to cover the area around the electric arc and prevent external oxygen from contacting the electric arc, thereby further reducing safety accidents caused by electric arc and improving the safety of power distribution equipment.

[0011] Preferably, the moving assembly includes a sliding frame, a sliding lead screw, a sliding motor, a moving lead screw, and a moving motor; the sliding frame is slidably mounted on the side wall of the cabinet door facing the cabinet body; the sliding lead screw is rotatably mounted on the cabinet door, passes through the sliding frame, and is threadedly connected to the sliding frame; the sliding motor is mounted on the cabinet door to drive the sliding lead screw to rotate; the moving lead screw is rotatably mounted on the sliding frame, and the moving block is slidably connected to the sliding frame; the moving lead screw passes through the moving block, and is threadedly connected to the moving block; the moving motor is mounted on the sliding frame to drive the moving lead screw to rotate.

[0012] By adopting the above technical solution, the sliding motor drives the sliding screw to rotate, thereby driving the sliding frame to move the moving block along the width direction of the cabinet; the moving motor drives the moving screw to rotate, thereby driving the moving block to move the arc extinguishing component along the height direction of the cabinet, thereby adjusting the orientation position of the arc extinguishing component so as to facilitate arc extinguishing treatment at various positions of the cabinet.

[0013] Preferably, the detection component includes a temperature sensor, a humidity sensor, a control component, and an alarm component mounted on the cabinet. The temperature sensor is located on a moving block to detect internal temperature data of the cabinet. The humidity sensor detects internal humidity data and high-temperature location data of the cabinet. The temperature sensor, humidity sensor, and alarm component are all controlled by the control component. The control component receives temperature data, high-temperature location data, and humidity data. When the temperature data and / or humidity data are higher than preset values, the control component drives the alarm component to issue an alarm message and activates the arc extinguishing component and the moving component.

[0014] By adopting the above technical solution, the temperature sensor detects the temperature data and high-temperature location inside the cabinet, and the humidity sensor detects the humidity data inside the cabinet. When the temperature data and / or humidity data are higher than the preset value, the control component promptly controls the warning component to issue an alarm. Using the data provided by the temperature sensor, the moving component is precisely controlled to move the arc extinguishing component to the corresponding position for arc extinguishing, thereby improving the overall intelligence of the equipment.

[0015] Preferably, the cabinet is equipped with an air exchange component for reducing the oxygen content inside the cabinet, and a heat dissipation component for dissipating heat.

[0016] By adopting the above technical solutions, the ventilation components reduce the oxygen content inside the cabinet, thereby reducing the occurrence of safety accidents caused by oxygen and electric arc inside the cabinet; the heat dissipation components dissipate heat from the cabinet, reducing the occurrence of electric arc and safety accidents inside the cabinet, and improving the safety of the power distribution equipment.

[0017] Preferably, the ventilation assembly includes a ventilation pipe, an exhaust pipe, a gas storage tank, an oxygen detector, a ventilation valve, and an exhaust valve.

[0018] By adopting the above technical solution, the gas storage tank and ventilation pipe supply flame-retardant nitrogen to the inside of the cabinet, and the oxygen inside the cabinet is discharged through the exhaust pipe. When the oxygen detector detects that the oxygen content inside the exhaust pipe is lower than the preset value, the control unit controls the ventilation valve and exhaust valve to close, thereby stopping the gas supply from the gas storage tank, which effectively reduces the oxygen content inside the cabinet. A flame-retardant environment with a large amount of flame-retardant gas and a small amount of combustion-supporting gas is formed inside the cabinet, thereby improving the safety of the power distribution equipment.

[0021] Preferably, a sealing strip is provided along the circumference of the cabinet door on the side wall facing the cabinet body, and a sealing ring groove is provided on the side wall of the cabinet body facing the cabinet door for the sealing strip to abut.

[0022] By adopting the above technical solution, the sealing strip is inserted into the sealing ring groove so that when the cabinet door and the cabinet body are closed, a sealed structure is formed inside the cabinet, reducing the adverse effects caused by external corrosive and high-temperature and humid gases entering the cabinet body.

[0023] Preferably, the side walls of the cabinet body and cabinet doors that are far apart from each other are made of high-strength composite materials, while the side walls of the cabinet body and cabinet doors that face each other are made of fireproof and insulating materials.

[0024] By adopting the above technical solutions, high-strength composite materials reduce the phenomenon of damage to power distribution equipment caused by external forces and reduce the phenomenon of damage to the internal structure of power distribution equipment; fireproof and insulating materials reduce the safety hazards caused by electric arcs inside the cabinet, thereby improving the safety of power distribution equipment.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The introduction of intelligent monitoring components reduces maintenance costs, improves the intelligence level of equipment, and significantly enhances the stability and safety of power distribution equipment in extreme environments. By setting up a detection component to monitor the environmental information inside the cabinet in real time, workers can be alerted to the internal status of the cabinet, thus facilitating timely prevention of safety accidents. Based on the information provided by the detection component, a moving component drives a moving block to move the arc extinguishing component to the location where the arc is generated. The arc extinguishing component then performs arc extinguishing, thereby reducing safety accidents caused by electric arcs inside the power distribution equipment and improving the safety of the power distribution equipment. This effectively reduces the impact of electric arc faults and the external environment on the equipment. By installing ventilation components to reduce the oxygen content inside the cabinet, the occurrence of safety accidents caused by oxygen and electric arcs inside the cabinet is reduced; heat dissipation components dissipate heat from the cabinet, reducing the occurrence of electric arcs and safety accidents inside the cabinet, and improving the safety of power distribution equipment.
