Technical Field

[0001] This utility model relates to the field of high-voltage switchgear technology, specifically a high-voltage switchgear equipped with a high-rated short-circuit breaking current circuit breaker. Background Technology

[0002] High-voltage switchgear is a device used in power systems for generating, transmitting, distributing, and converting electrical energy. It contains multiple circuit breakers and is monitored by a central controller. The electrical equipment inside the cabinet is connected by wiring harnesses and can withstand high voltages, allowing for the safe distribution of electrical energy to other locations.

[0003] When a short circuit occurs in a power system, the high-rated short-circuit breaking current circuit breaker installed inside can quickly cut off the current at the fault point, preventing the electrical equipment connected to both ends of the wiring harness from burning out. However, most of the partition panels inside such high-voltage switchgear are directly fixed, and the layout inside the cabinet cannot be adjusted according to needs. The wiring harnesses between various instruments are also haphazardly intertwined, making it quite inconvenient to organize.

[0004] Now, a new type of high-voltage switchgear equipped with a high-rated short-circuit breaking current circuit breaker is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-voltage switchgear equipped with a high-rated short-circuit breaking current circuit breaker to solve the problem of fixed internal structure mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-voltage switchgear equipped with a high-rated short-circuit breaking current circuit breaker, comprising a cabinet, a top plate horizontally fixed at the top of the cabinet, and a partition plate welded between the bottom rear of the top plate and the cabinet, positioning holes longitudinally provided at the front of both sides of the cabinet interior, four sets of support plates horizontally arranged inside the cabinet, and bolts threadedly connected to the front of both sides of the support plates, a sleeve longitudinally fixed at the center of the front end of the partition plate, a sliding sleeve movably sleeved at the front end of the support plate, and an assembly plate fixed at the front end of the sliding sleeve, with a circuit breaker mounted on the assembly plate, bolts threadedly connected to both sides of the front end of the sliding sleeve, and a wire harness fixedly passing through the assembly plate at the rear of the circuit breaker.

[0007] As a further technical solution of this utility model, the sliding sleeve moves horizontally to the left and right along the front of the support plate, and the side of the bolt is embedded in the positioning hole.

[0008] As a further technical solution of this utility model, a frame is fixed between the upper left side of the cabinet body and the top plate, and a rotating plate is movably connected between the frame and the top plate. A controller is placed on the top of the rotating plate. A limit block is fixed at the upper right corner of the cabinet body, and a pin is movably inserted into the upper part of the limit block. A hole is longitudinally provided on the right side inside the rotating plate.

[0009] As a further technical solution of this utility model, the partition is provided with a guide hole inside, the wire harness is embedded in the guide hole, silicone sleeves are fixed longitudinally on both sides of the rear of the cabinet, and a groove is provided at the center of the silicone sleeve. A cover is movably hinged to the left side of the rear of the silicone sleeve, and a locking block is fixed on the right side of the cover. A second protrusion is provided on the left side of the silicone sleeve, and a first protrusion is provided on the right side of the silicone sleeve.

[0010] As a further technical solution of this utility model, the hole diameter of the card block matches that of protrusion one and protrusion two, and the cover covers the outside of the silicone sleeve.

[0011] As a further technical solution of this utility model, a cabinet door is movably hinged to the right side of the front end of the cabinet body, and a channel is longitudinally arranged on the front right side inside the cabinet door. A sliding plate is movably inserted into the channel, and a pull rod is longitudinally fixed to the right side of the sliding plate. Insert rods are fixed to the top and bottom of the left side of the pull rod, respectively. Slots are respectively provided inside the upper right corner and lower right corner of the cabinet door. A glass plate is fixed to the top rear of the inside of the cabinet door, and a dust filter is fixed between the bottom of the glass plate and the cabinet door.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the high-voltage switchgear equipped with a high rated short-circuit breaking current circuit breaker not only facilitates the adjustment of the internal structure of the cabinet and protects the wiring points at the rear of the cabinet, but also allows for the adjustment of the door panel's state;

[0013] (1) By installing a circuit breaker on the assembly plate, the support plate is moved longitudinally along both sides of the inner wall of the cabinet, and the position is locked with bolt one. The sliding sleeve in front of the support plate is adjusted horizontally to adjust the position of the assembly plate and the circuit breaker. The second rotating bolt is tightened and reinforced, and the rear of the support plate is horizontally embedded in the corresponding sleeve. The circuit breaker's wire harness passes through the guide hole to connect to the outside and is electrically connected to the controller above. The rotating plate is rotated horizontally along the inside of the frame to remove the controller and other items for inspection and maintenance. After aligning with the limit block, the pin is inserted between the limit block and the hole to prevent the rotating plate from automatically rotating out, thus realizing the adjustability of the internal structure of the cabinet.

[0014] (2) By fixing silicone sleeves longitudinally on both sides of the rear of the cabinet, after adjusting the height of the support plate, the guide hole can be selected and the wire harness of the controller can be led out. Multiple wire harnesses are passed through the partition inside the cabinet and are concentrated in the groove of the elastic silicone sleeve for limiting. If it is not necessary to lead out the wire harness from here, the cover is reset so that the clip on the side of the cover is engaged on the first protrusion. After opening, the clip on the cover is engaged on the second protrusion.

[0015] (3) A cabinet door is hinged to the right side of the front end of the cabinet. The cabinet door installed on the right side of the front end of the cabinet is divided into inner and outer layers. By pinching the pull rod, the slide can be pulled out horizontally along the channel, so that the glass plate and dust filter can be exposed. This makes it convenient to view the data above the controller screen and also allows for heat dissipation and ventilation. After the process is completed, the slide is reset so that the upper and lower rods are respectively embedded in the slots for limiting, ensuring the sealing and protection performance of the cabinet.

A limit block 20 is fixed in the upper right corner of the cabinet 1, and a pin 19 is movably inserted into the upper part of the limit block 20. A hole 23 is longitudinally provided on the right side of the rotating plate 13.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the support plates 2 are moved longitudinally along both sides of the inner wall of the cabinet 1, and then the position is locked with bolt 6. The sliding sleeve 9 in front of the support plate 2 is adjusted horizontally, and the positions of the assembly plate 8 and the circuit breaker 22 are adjusted. The second bolt 10 is rotated to tighten and reinforce, and the rear of the support plate 2 is horizontally embedded in the corresponding sleeve 3. The wiring harness 11 of the circuit breaker 22 passes through the guide hole 4 to connect to the outside and has an electrical connection with the controller 14 above. The rotating plate 13 is rotated horizontally along the inside of the frame 21, and the controller 14 and other items can be taken out for inspection and maintenance. After aligning with the limit block 20, the pin 19 is inserted between the limit block 20 and the hole 23 to prevent the rotating plate 13 from automatically rotating out.

[0025] The partition 7 has a guide hole 4 inside, and the wire harness 11 is embedded in the guide hole 4. The two sides of the rear of the cabinet 1 are respectively fixed with silicone sleeves 24 longitudinally, and the center of the silicone sleeve 24 is provided with a groove 25. The left side of the rear of the silicone sleeve 24 is movably hinged with a cover 29, and the right side of the cover 29 is fixed with a locking block 26. The left side of the silicone sleeve 24 is provided with a second protrusion 28, and the right side of the silicone sleeve 24 is provided with a first protrusion 27. The hole diameter of the locking block 26 matches the first protrusion 27 and the second protrusion 28. The cover 29 covers the outside of the silicone sleeve 24.

[0026] Specifically, such as Figure 1 and Figure 3As shown, after adjusting the height of the support plate 2, the guide hole 4 can be selected and the wire harness 11 connecting the controller 14 can be led out. Multiple wire harnesses 11 are passed through the partition 7 inside the cabinet 1 and are concentrated in the slot 25 of the elastic silicone sleeve 24 for limiting. If it is not necessary to lead out the wire harness 11 from here, the cover 29 is reset to protect the silicone sleeve 24 on the rear surface of the cabinet 1.

[0027] A cabinet door 15 is hinged to the right side of the front end of the cabinet body 1. A channel 18 is longitudinally arranged on the front right side inside the cabinet door 15.

Afterwards, the guide hole 4 can be selected and the connection can be extended. The wiring harness 11 of the controller 14 is passed through the partition 7 inside the cabinet 1 and is concentrated in the slot 25 of the elastic silicone sleeve 24 for limiting. If it is not necessary to lead the wiring harness 11 out from here, the cover 29 is reset so that the locking block 26 on the side of the cover 29 is engaged with the first protrusion 27. After opening, the locking block 26 of the cover 29 is engaged with the second protrusion 28. The cabinet door 15 installed on the right side of the front of the cabinet 1 is divided into inner and outer layers. By pinching the pull rod 16, the slide plate 17 can be pulled out horizontally along the channel 18, so that the glass plate 30 and the dust filter 32 are exposed. This makes it convenient to view the data above the screen of the controller 14 and also allows for heat dissipation and ventilation. After finishing, the slide plate 17 is reset so that the upper and lower insertion rods 33 are respectively engaged in the slots 31 for limiting, ensuring the sealing and protection performance of the cabinet 1.
