Description

Technical Field

[0001] This invention relates to the field of transformer cabinet technology, and more particularly to a power distribution transformer JP cabinet and its usage method. Background Technology

[0002] JP cabinets (integrated distribution boxes) are key supporting equipment on the low-voltage side of transformers, widely used at the end of distribution networks, undertaking functions such as power distribution, metering, protection, and control. Since JP cabinets are typically installed outdoors, they are exposed to harsh weather conditions such as wind, sand, dust, and lint for extended periods. This can easily lead to blockage of their heat dissipation structure, causing internal temperatures to rise and affecting the safe operation and service life of the transformer and related electrical components.

[0003] Currently, common JP cabinets mainly rely on natural ventilation or fixed heat dissipation holes for heat dissipation. Although some equipment has fans installed on the top of the cabinet to enhance heat dissipation, dust and debris easily accumulate in the heat dissipation holes during actual use, thus affecting ventilation efficiency. In existing technologies, the heat dissipation structure is usually maintained by manual periodic cleaning or external blowing, which is cumbersome and poses safety hazards. Automatic cleaning devices mostly use a single brush or air blowing structure, which is difficult to penetrate deep into the heat dissipation holes for effective unblocking, especially when dust becomes damp and hardened, making it even more difficult to remove.

[0004] Therefore, there is an urgent need for a power distribution transformer JP cabinet that can efficiently, automatically, and comprehensively clean the heat dissipation structure to improve the heat dissipation performance and long-term operational reliability of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a power distribution transformer JP cabinet and its usage method. By setting up a needle column moving component, the needle column is driven to insert into the heat dissipation holes of the heat sink plate, which can directly push out the dust, lint and other blockages accumulated inside the heat dissipation holes to the outside of the cabinet. The brush moving cleaning component, together with the needle column rotation driving component, can first brush off the dust on one side of the needle column after the needle column has completed the initial unblocking, and then drive the needle column to rotate 90 degrees so that the brush can clean the other side again, thus achieving all-round cleaning of the needle column.

[0006] To achieve the above objectives, the present invention provides a power distribution transformer JP cabinet, including a transformer cabinet body, a heat sink, a brush moving cleaning assembly, a pin moving assembly, and a pin rotating drive assembly. A fan is provided on the top of the transformer cabinet body. Heat sinks are connected to two opposite side walls of the transformer cabinet body. Each heat sink is equipped with a brush moving cleaning assembly, a pin moving assembly, and a pin rotating drive assembly. Brush moving cleaning assemblies are provided on the two outer walls of the transformer cabinet body, and the brush moving cleaning assembly, pin moving assembly, and pin rotating drive assembly are all arranged opposite to the heat sinks. Pin moving assemblies and pin rotating drive assemblies are provided on the two inner walls of the transformer cabinet body.

[0007] Preferably, the heat sink has multiple heat dissipation holes arranged in a matrix.

[0008] Preferably, the brush moving cleaning assembly includes a fixing plate, a brush body, a guide post, a screw, a motor, and a partition. The two fixing plates are arranged opposite to each other and fixedly connected to the outer wall of the transformer cabinet. The guide post passes through one end of the brush body, allowing the brush body to move along the guide post. The screw is rotatably connected between the two fixing plates and passes through the other end of the brush body and is threadedly connected to the brush body. One end of the screw is drively connected to the output shaft of the motor.

[0009] Preferably, the bottom of the brush body is provided with multiple blocks, and the multiple blocks are located between every two rows of adjacent heat dissipation holes, and the size of the blocks matches the spacing of the heat dissipation holes.

[0010] Preferably, the needle column moving assembly includes a connecting plate and two oppositely arranged electric telescopic rods. The fixed ends of the electric telescopic rods are fixedly connected to the inner wall of the transformer cabinet, and the fixed ends of the two electric telescopic rods are respectively located on both sides of the heat dissipation plate. The movable ends of the electric telescopic rods are fixedly connected to the wall of the connecting plate, and the movable ends of the electric telescopic rods are respectively located at both ends of the same side wall of the connecting plate.

[0011] Preferably, a plurality of pins are rotatably connected to one side wall of the connecting plate via bearings, and the number and position of the pins match the number and position of the heat dissipation holes of the heat sink.

[0012] Preferably, the needle column rotation drive assembly includes a guide plate, a rack, a gear, a connecting rod, and a second electric telescopic rod. The guide plate is fixedly connected to the side wall of the connecting plate. The guide plate has multiple guide grooves in the vertical direction. Each rack is horizontally arranged, and one end of each rack is slidably connected in the guide groove. The other end of the rack is fixedly connected to the connecting plate. The fixed end of the second electric telescopic rod is fixedly connected to the connecting plate, and the movable end of the second electric telescopic rod is fixed to the middle of the connecting rod. The movable end of the second electric telescopic rod moves in the horizontal direction.

[0013] Preferably, the other end of the needle column is fixedly connected to a gear, and each row of gears meshes with each row of racks for transmission.

[0014] Preferably, the connecting plate is also provided with multiple ventilation slots; the motor, fan, electric telescopic rod one, and electric telescopic rod two are all electrically connected to the controller; and the front of the transformer cabinet is provided with an openable cabinet door.

[0015] A method for using a power distribution transformer JP cabinet includes the following steps: Step 1: When a large amount of dust accumulates in the heat dissipation holes of the heat sink, the controller drives the heat sink on one side of the transformer cabinet to perform cleaning work, while the heat sink on the other side needs to wait; the controller controls the movable end of the electric telescopic rod in the needle column moving assembly to extend, so that the needle column is inserted into the heat dissipation hole of the heat sink, and the needle column can push the accumulated material in the heat dissipation hole to the outside. Step 2: The controller controls the motor to rotate, the motor drives the screw to rotate, and the screw drives the brush body to move from one side of the heat sink to the other side. Because it is divided into sections between each row of heat sink holes, it can clean the dust accumulation on the needle column. Step 3: The controller controls the extension of the movable end of the electric telescopic rod 2, which drives the rack to move. The rack drives the gear to rotate 90 degrees, causing the needle column to rotate 90 degrees. Step 4: The controller controls the motor to rotate in the opposite direction, so that the brush body moves from one side of the heat sink to the other side, thereby cleaning the dust accumulation on the other side of the needle column. Step 5: After cleaning is completed, the controller controls the needle column moving assembly and the needle column rotation drive assembly to reset, and then the cleaning work of the heat sink on the other side is carried out.

[0016] The advantages and positive effects of the JP switchgear for power distribution described in this invention are: 1. By setting up a needle column moving component, the needle column is driven to insert into the heat dissipation holes of the heat dissipation plate, which can directly push out the dust, lint and other blockages accumulated inside the heat dissipation holes to the outside of the cabinet. This solves the problem that traditional cleaning methods can only clean the surface and cannot clear the blockage inside the holes, and significantly improves the recovery ability of the heat dissipation channel.

[0017] 2. The brush moving cleaning component, together with the needle column rotation drive component, can first brush away the dust on one side of the needle column after the needle column has completed the initial unblocking, and then drive the needle column to rotate 90 degrees so that the brush can clean the other side again. This achieves all-round cleaning of the needle column and effectively prevents the contaminants remaining on the needle column from falling back into the heat dissipation holes during the resetting process.

[0018] 3. The motor, electric telescopic pole, fan and other components are all electrically connected to the controller. The entire cleaning process - including needle insertion, brush movement, needle rotation, brush return and component reset - can be completed automatically without manual intervention, reducing the workload and operational risks of maintenance personnel.

[0019] 4. The transformer cabinet is equipped with independent brush moving cleaning components, needle column moving components and needle column rotation drive components on both sides. The control method stipulates that the other side is cleaned only after one side is cleaned. This ensures that at least one side of the cabinet maintains normal heat dissipation during the cleaning process and avoids the problem of a sudden drop in the overall heat dissipation capacity during cleaning.

[0020] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description
