Description

Technical Field

[0001] This invention relates to the field of electrical control cabinet technology, specifically a high-voltage electrical control cabinet. Background Technology

[0002] A control cabinet is a device that assembles switching equipment, measuring instruments, protective electrical devices, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, facilitate maintenance, and not endanger the safety of personnel and surrounding equipment. During normal operation, circuits can be connected or disconnected using manual or automatic switches. In case of faults or abnormal operation, protective electrical devices will disconnect the circuit or trigger an alarm. Measuring instruments can display various operating parameters, allow adjustment of certain electrical parameters, and provide alerts or signals for deviations from normal operating conditions.

[0003] Existing control cabinets generate a lot of heat from their internal electrical components during operation. Traditional heat dissipation methods are slow and cannot dissipate heat in time, resulting in low operating efficiency of components. Over time, this will lead to component aging and even fire. Existing control cabinets do not have fire extinguishing capabilities, and the fire spreads along the wires. By the time staff discover the fire, it is too late, resulting in significant losses. Therefore, a high-voltage electrical control cabinet is needed. Summary of the Invention

[0004] (a) Technical problems to be solved In view of the shortcomings of the prior art, the present invention provides a high-voltage electrical control cabinet that solves the problem that existing control cabinets do not have fire extinguishing function, thus preventing the spread of fire and reducing losses.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a high-voltage electrical control cabinet, comprising a control cabinet, a partition disposed inside the control cabinet near the top, a gas cylinder disposed on the top of the partition, a connecting pipe connected to the outlet end of the gas cylinder, a fire sprinkler head disposed on the surface of the connecting pipe, movable plates vertically slidably connected to both sides of the inner wall of the partition, a connecting plate fixedly connected between the bottom ends of the two movable plates, a fixed plate fixedly connected to the top of the movable plates, triggering devices fixedly connected to both sides of the bottom of the partition, a slot adapted to the triggering device disposed on the surface of the fixed plate, when the triggering device is activated, separating from the slot, the movable plate sliding downwards, heat dissipation holes disposed on both sides of the control cabinet, ventilation holes disposed on the surface of the movable plates, and connection sockets disposed at the bottom of both sides of the control cabinet. A fixed base is fixedly connected to the center of the bottom of the control cabinet. Connecting pipes are fixedly connected to the two sides of the fixed base and the connecting socket. A connecting terminal is provided on one side of the connecting socket, and a matching connecting plug is provided on the other side. A circular plate is slidably connected to the surface of the connecting pipe and the side near the connecting socket. A push rod is fixedly connected to one side of the circular plate. A through hole matching the push rod is provided in the connecting socket. A mounting plate is fixedly connected to the top of the fixed base. Fixed hooks are rotatably connected to both sides of the mounting plate. A circular block is slidably connected to the surface of the connecting pipe. A spring is provided between one side of the fixed base and the circular block. The circular block compresses the spring through the fixed hook. The fixed hook separates from the circular block as the connecting plate falls. After separation, the circular block slides along the length of the connecting pipe and strikes the circular plate. The push rod pushes the connecting plug out and separates it from the connecting socket.

[0006] Preferably, the spacing between the heat dissipation holes is equal to the spacing between the ventilation holes. When the slot engages with the trigger device, the ventilation hole is located at the position directly corresponding to the heat dissipation hole. The falling movement distance of the movable plate is less than the spacing between adjacent ventilation holes and greater than the width of the heat dissipation hole.

[0007] Preferably, the circumference of the circular block is provided with a fixing groove that matches the fixing hook, and a torsion spring is provided between the fixing hook and the mounting plate, the spring being fixed to one side of the fixing seat.

[0008] Preferably, the surface roughness of the connecting pipe, the inner wall of the circular block, and the inner wall of the circular plate is less than 1.6, and the surface of the fixing seat is provided with wire through holes, which are connected to the connecting pipe.

[0009] Preferably, the inner wall of the control cabinet is provided with a trigger control switch, the top of the partition is provided with an independent power supply, multiple trigger control switches are provided and connected in parallel, and the triggering device is connected in series with the trigger control switch and electrically connected to the independent power supply.

[0010] Preferably, the triggering device includes a fixed frame, an electric push rod is provided at the bottom inside the fixed frame, a connecting frame is fixedly connected to the working end of the electric push rod, and a locking rod is fixedly connected to both ends of the connecting frame. One end of the locking rod is slidably connected to the fixed frame, and the other end of the locking rod is slidably connected to the inner wall of the control cabinet.

[0011] Preferably, the trigger control switch is a normally open snap-action temperature control switch.

[0012] Preferably, the surface of the connecting pipe is provided with a pressure gauge and a valve.

[0013] Preferably, the gas tank is provided with compressed flame-retardant gas.

[0014] (III) Beneficial Effects This invention provides a high-voltage electrical control cabinet. It has the following beneficial effects: The fire extinguishing device is composed of a gas cylinder, connecting pipes, and fire sprinkler heads. The gas cylinder contains flame-retardant gas. When the temperature inside the control cabinet reaches a certain value, the fire sprinkler heads activate, spraying the flame-retardant gas into the cabinet to extinguish the fire. Simultaneously, a trigger control switch activates the triggering device, causing a movable plate to slide down and block the ventilation holes, preventing outside air from entering and preventing the flame-retardant gas from overflowing, thus improving the flame-retardant extinguishing effect. As the movable plate slides down, the connecting plate collides with the fixed hook, separating the fixed hook from the circular block. The circular block, under the action of a spring, moves along the connecting pipe and impacts the circular plate. This causes a push rod on one side of the circular plate to push the connecting plug out of the connecting socket, achieving separation of the control cabinet from the cable. This prevents fire from spreading along the cable and avoids the problem of incomplete isolation caused by pre-drilled wiring holes in traditional control cabinets. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-6 This invention provides a technical solution: a high-voltage electrical control cabinet, including a control cabinet 1. A partition 2 is provided inside the control cabinet 1 near the top. A gas tank 3 is provided on the top of the partition 2. The gas tank 3 contains compressed flame-retardant gas, which is one of carbon dioxide, nitrogen, argon, or halon gas. The outlet end of the gas tank 3 is connected to a connecting pipe 4. A fire sprinkler head 5 is provided on the surface of the connecting pipe 4. Movable plates 6 are vertically slidably connected to both sides of the inner wall of the partition 2. Specifically, three movable plates 6 are provided and arranged side by side. A placement plate is provided inside the control cabinet 1. The two ends of the placement plate are located between two adjacent movable plates 6, which realizes the fixation of the placement plate. The surface of the placement plate can be used to install various electrical components.

[0019] A connecting plate 7 is fixedly connected between the bottom ends of the two movable plates 6, and a fixed plate 8 is fixedly connected to the top of the movable plate 6. Triggering devices 12 are fixedly connected to the bottom sides of the partition 2. The surface of the fixed plate 8 is provided with slots 11 adapted to the triggering devices 12. When the triggering devices 12 are activated, they separate from the slots 11, and the movable plates 6 slide downwards. Heat dissipation holes 9 are provided on both sides of the control cabinet 1, and ventilation holes 10 are provided on the surface of the movable plates 6 for normal heat dissipation inside the control cabinet 1. Connecting sockets 13 are provided at the bottom of both sides of the control cabinet 1. A fixed base 14 is fixedly connected to the bottom center of the control cabinet 1. Connecting pipes 15 are fixedly connected between the two sides of the fixed base 14 and the connecting socket 13. A connecting terminal 16 is provided on one side of the connecting socket 13. The surface of the fixed base 14 is provided with wire holes, and the wire holes are connected to the connecting pipes 15. The various electrical cables in the control cabinet 1 pass through the wire holes and are electrically connected to the connecting terminal 16 in the connecting socket 13 through the connecting pipes 15. A matching connecting plug 19 is provided on one side of the connecting socket 13, and the connecting plug 19 is connected to the corresponding external cable.

[0020] A circular plate 17 is slidably connected to the surface of the connecting pipe 15 and the side near the connecting socket 13. A push rod 18 is fixedly connected to one side of the circular plate 17. A through hole adapted to the push rod 18 is provided in the connecting socket 13. A mounting plate 22 is fixedly connected to the top of the fixing base 14. Fixing hooks 23 are rotatably connected to both sides of the mounting plate 22. A circular block 20 is slidably connected to the surface of the connecting pipe 15. A spring 21 is provided between one side of the fixing base 14 and the circular block 20. A fixing hook is provided around the periphery of the circular block 20. The mounting slot 23 is adapted to the mounting plate 22 and a torsion spring 24 is provided between the mounting hook 23 and the mounting plate 22. The spring 21 is fixed on one side of the mounting base 14. The round block 20 compresses the spring 21 through the mounting hook 23. The mounting hook 23 separates from the round block 20 through the falling of the connecting plate 7. After separation, the round block 20 slides along the length of the connecting tube 15 and hits the round plate 17. The push rod 18 pushes out the connecting plug 19 and separates it from the connecting socket 13, realizing the physical disconnection of the line and preventing the fire from spreading along the cable.

[0021] The spacing between the heat dissipation holes 9 and the spacing between the ventilation holes 10 are equal. When the slot 11 engages with the trigger device 12, the ventilation hole 10 is located directly corresponding to the heat dissipation hole 9. The falling movement distance of the movable plate 6 is less than the spacing between adjacent ventilation holes 10 and greater than the width of the heat dissipation hole 9, ensuring that the heat dissipation hole 9 is blocked when it falls, thus achieving isolation from the outside world.

[0022] The surface roughness of the connecting tube 15, the inner wall of the circular block 20, and the inner wall of the circular plate 17 is less than 1.6, which reduces friction and ensures the kinetic energy of the circular block 20 as much as possible. The energy is transferred to the circular plate 17, which pops out the connecting plug 19 and disconnects the cable.

[0023] The inner wall of the control cabinet 1 is equipped with a trigger control switch 25, and the top of the partition 2 is equipped with an independent power supply 26. Multiple trigger control switches 25 are set and connected in parallel. The trigger device 12 is connected in series with the trigger control switch 25 and electrically connected to the independent power supply 26. The trigger control switch 25 is a normally open snap-action temperature control switch. The trigger control switches 25 are evenly distributed in the control cabinet 1 to ensure that any abnormal high temperature or fire source can be detected in any location in a timely manner to extinguish the fire.

[0024] The triggering device 12 includes a fixed frame 121. An electric push rod 122 is provided at the bottom inside the fixed frame 121. A connecting frame 124 is fixedly connected to the working end of the electric push rod 122. A locking rod 123 is fixedly connected to both ends of the connecting frame 124. One end of the locking rod 123 is slidably connected to the fixed frame 121, and the other end of the locking rod 123 is slidably connected to the inner wall of the control cabinet 1. When the electric push rod 122 is powered on, it pushes the connecting frame 124 to separate the locking rod 123 from the locking slot 11.

[0025] The surface of the connecting pipe 4 is equipped with a pressure gauge 27 and a valve 28, and the pressure gauge facilitates daily inspection.
