Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power distribution cabinet technology, and in particular relates to a power distribution cabinet with built-in leakage protection function. Background Technology
[0002] With the acceleration of urbanization and the continuous development of the power system, the distribution cabinet, as the core equipment for power distribution and control, is widely used in industrial, commercial and civil buildings. Its operational safety is directly related to the stability of the power supply system and the safety of people and property.
[0003] Modern power distribution cabinets integrate a wide variety of electrical components, with extremely dense wiring and a complex overall structure. If a leakage occurs, it will not only cause equipment damage and unnecessary power loss, but more seriously, it may also cause electric shock accidents, posing a direct threat to the lives of people in the vicinity, and may even induce electrical fires, seriously endangering the safety of building facilities.
[0004] Therefore, a distribution cabinet with built-in leakage protection is particularly needed to solve the above problems. Utility Model Content
[0005] To overcome the shortcomings of complex internal structure and dense wiring in distribution cabinets, which can easily lead to equipment damage, electric shock accidents or electrical fires and pose significant safety hazards in the event of leakage, this utility model provides a distribution cabinet with built-in leakage protection function.
[0006] This utility model is achieved through the following technical means: A distribution cabinet with built-in leakage protection function includes a cabinet body, a cabinet door, a mounting plate, a heat dissipation frame, and switches. The cabinet door is rotatably located at the front of the cabinet body. The mounting plate is installed at the rear of the cabinet body. Multiple large and small switches are neatly arranged on the front of the mounting plate. The heat dissipation frame is installed on one side of the mounting plate and surrounds the multiple switches. It also includes a detection plate, indicator lights, a controller, an alarm, a camera, an electric slide rail one, an electric slider one, an electric slide rail two, an electric slider two, and a toggle block. Two symmetrically distributed detection plates are installed at the bottom of each large switch, and at the bottom of each small switch... A detection board is installed, with an indicator light on each detection board. The controller is installed in the lower part of the cabinet, the alarm is installed in the upper part of the cabinet, and the camera is installed on the side of the cabinet door facing the inside of the cabinet. The camera lens is directly facing the mounting board and multiple switch areas. Electric slide rail one is vertically installed on the front side of the heat dissipation frame, and electric slider one is slidably mounted on it. Electric slide rail two is horizontally installed on electric slider one, and electric slider two is slidably mounted on it. The detection board, indicator light, alarm, camera, electric slide rail one, electric slider one, electric slide rail two, and electric slider two are all electrically connected to the controller. A toggle block is installed at the rear of electric slider two.
[0007] In a preferred embodiment of the present invention, a cable feeder is also included, which is installed on the lower part of the mounting plate.
[0008] In a preferred embodiment of this utility model, the heat sink frame is made of a metal material with good thermal conductivity.
[0009] In a preferred embodiment of this utility model, the heat dissipation frame is provided with a plurality of evenly distributed heat dissipation holes.
[0010] In a preferred embodiment of this invention, the vertical running trajectory plane of the toggle intersects with the plane where the operating handle of the switch is located.
[0011] In a preferred embodiment of this utility model, the controller has a built-in wireless communication module.
[0012] Beneficial effects: 1. By setting up an intelligent leakage protection mechanism consisting of a detection board, indicator lights, controller, alarm, camera, electric slide rail one, electric slider one, electric slide rail two, electric slider two and toggle block, the automatic monitoring and rapid response to leakage faults of the switch can be realized. It has the functions of visual fault prompts, remote alarm and mechanical forced power cut-off, which significantly improves the intelligence level and safety protection capability of the distribution cabinet, effectively prevents electric shock risk and electrical fire, and protects the safety of surrounding personnel and building facilities.
[0013] 2. By setting up a heat dissipation frame, the densely installed switches are centrally protected and heat dissipation is guided. Combined with materials with good thermal conductivity and multiple heat dissipation holes, the air convection inside the cabinet is enhanced, effectively reducing the operating temperature and preventing the performance of components from deteriorating due to high temperature, thus ensuring the long-term stable operation of the power distribution system.
[0014] 3. By setting up an inlet rack, power inlets can be fixed and classified in an orderly manner, avoiding wire crossing, tangling or uneven stress, and improving the standardization, safety and convenience of later maintenance. Attached Figure Description

Detailed Implementation
[0023] Example: A distribution cabinet with built-in leakage current protection function, such as Figures 1-7As shown, the system includes a cabinet 1, a cabinet door 2, a mounting plate 3, a heat dissipation frame 4, switches 5, and an inlet bracket 6. The cabinet door 2 is hinged and located at the front of the cabinet 1, allowing for easy opening and closing for convenient internal inspection and maintenance. The mounting plate 3 is bolted to the rear of the cabinet 1. Multiple large switches 5 (such as molded case circuit breakers and frame circuit breakers) and small switches 5 (such as miniature circuit breakers and residual current devices) are neatly arranged on the front of the mounting plate 3, forming a complete power distribution and control circuit. The heat dissipation frame 4 is bolted to the front of the mounting plate 3 and has multiple evenly distributed heat dissipation holes. The heat dissipation frame 4 surrounds the multiple switches 5 and uses materials with good thermal conductivity. Made of metallic materials (such as aluminum alloy or galvanized steel sheet), it has good thermal conductivity and corrosion resistance. The cable tray 6 is fixed to the lower right side of the mounting plate 3 by bolts, which can centrally fix and organize the power cables introduced from the outside of the cabinet 1, avoid messy wiring, and improve wiring standardization and safety. It also includes a detection plate 7, indicator light 8, controller 9, alarm 10, camera 11, electric slide rail one 12, electric slider one 13, electric slide rail two 14, electric slider two 15, and toggle block 16. Each large switch 5 has two symmetrically distributed detection plates 7 fixed to its lower part by bolts, and each small switch 5 has one detection plate 7 fixed to its lower part by bolts. The testing board 7 integrates a leakage current sensor (such as a zero-sequence current transformer) capable of sensing minute leakage currents. Each testing board 7 has an indicator light 8 fixed to it by bolts; when a leakage current is detected by the testing board 7, the indicator light 8 automatically illuminates. The controller 9 is fixed to the lower horizontal surface inside the cabinet 1 by bolts. The alarm 10 is fixed to the upper part of the cabinet 1 by bolts. The camera 11 is fixed to the side of the cabinet door 2 facing the inside of the cabinet 1 by bolts, with the lens of the camera 11 facing the mounting plate 3 and the area of multiple switches 5. Electric slide rail 12 is vertically fixed to the front right side of the heat dissipation frame 4 by bolts, and an electric slider 13 is slidably mounted on it. Electric slide rail 2 14 is horizontally fixed to the electric slide rail 4 by bolts. Electric slider 15 is slidably mounted on the sliding slider 13. The detection plate 7, indicator light 8, alarm 10, camera 11, electric slide rail 12, electric slider 13, electric slide rail 14, and electric slider 15 are all electrically connected to the controller 9. The controller 9 has a built-in wireless communication module, which can upload leakage alarm information and fault location to the remote monitoring platform in real time to realize remote early warning and intelligent management. The toggle block 16 is fixed to the rear of the electric slider 15 by bolts, and the vertical running trajectory plane of the toggle block 16 intersects with the plane where the operating handle of the switch 5 is located, ensuring that the toggle block 16 can reliably move the operating handle of the switch 5 when it moves upward in the lateral position.
[0024] During normal operation of the power distribution cabinet, each detection board 7 continuously monitors the leakage current of the corresponding switch 5 circuit. When the insulation of the line connected to a certain switch 5 is damaged or grounded, leakage current is generated in its circuit. The detection board 7 at the bottom of the switch 5 immediately detects the abnormal signal, controls the indicator light 8 on it to light up automatically, and sends the leakage signal to the controller 9 at the same time.
[0025] After receiving the alarm signal from the detection board 7, the controller 9 simultaneously activates the camera 11 to acquire images. The camera 11 uses image recognition technology to lock the position of the light, confirms the specific switch 5 that is leaking electricity, and feeds back the position information to the controller 9. The controller 9 calculates the precise position of the switch 5 in two-dimensional space according to the preset coordinate mapping relationship.
[0026] Subsequently, controller 9 activates electric slide rail 12 and electric slide rail 2 14. First, it controls electric slider 2 15 to drive block 16 to slide horizontally to the predetermined position directly below the switch 5, completing the horizontal positioning. After positioning, controller 9 controls electric slider 13 to slide upward, driving electric slide rail 2 14 and electric slider 2 15 to move vertically upward as a whole, so that block 16 contacts the operating handle of the switch 5 and continues to push upward, forcibly switching it from the closed state to the open state, cutting off the power supply of the fault circuit, and preventing the accident from escalating further.
[0027] At the same time, the controller 9 triggers the alarm 10 to issue an audible and visual alarm, and sends the leakage alarm information and fault location to the remote monitoring center in real time through the wireless communication module, reminding the operation and maintenance personnel to come to the site for troubleshooting and handling in a timely manner. After the fault is cleared, the power supply is restored by manual closing of the circuit breaker, the system is reset, and the normal monitoring status is restored.
