Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to a ventilation plate for high-voltage switchgear. Background Technology

[0002] High-voltage switchgear is a commonly used power transmission equipment in power transmission systems. To prevent accidental human contact with the high-voltage live parts of the switchgear and to prevent foreign objects from entering the switchgear and causing short circuits, switchgear is currently mostly equipped with a fully enclosed metal enclosure. The general standard requires the metal enclosure to reach the IP4X protection level, which means that it can block objects such as metal wires with a diameter greater than 1.0 mm or narrow strips with a thickness greater than 1.0 mm from entering. This greatly restricts the heat dissipation efficiency of the switchgear.

[0003] Moreover, the high-voltage switchgear is divided into multiple chambers for installing different electrical devices. The ventilation plates between the chambers have openings to allow air circulation within the high-voltage switchgear. The openings in the ventilation plates can meet the ventilation requirements. However, when a fault occurs in one of the electrical chambers of the high-voltage switchgear, an electric arc will be generated due to the high voltage. The electric arc can easily pass through the openings in the ventilation plates, thereby causing damage to other chambers.

[0004] Therefore, a ventilation panel for high-voltage switchgear is proposed for safe ventilation.

[0005] For example, the prior art Chinese patent publication number "CN221688098U" provides a high-voltage switchgear ventilation plate and a high-voltage switchgear, including a first plate and a second plate. The first plate has several through holes. The first plate and the second plate are connected by a first connecting part to form a ventilation cavity. The first plate is fixed to the high-voltage switchgear by a second connecting part.

[0006] The device has a first plate that is directly connected to the high-voltage switchgear for ventilation, and a second plate to prevent arcing from breaking down the first plate. It can simultaneously meet the ventilation needs and the need to prevent arcing from breaking down inside the high-voltage switchgear, and has good application value.

[0007] Existing high-voltage switchgear ventilation panels have a relatively simple structure. Installed inside the high-voltage switchgear, they can only ventilate one side of the chamber, failing to provide ventilation and heat dissipation to the chambers on both sides. Moreover, the electric arc generated by the high voltage can easily pass through the openings of the ventilation panel and damage the partition plate, causing damage to the partition plate. They fail to provide protection for the partition plate and facilitate easy disassembly, replacement, and maintenance. In addition, the connection position between the ventilation panel and the inner side of the external high-voltage switchgear is relatively fixed and inconvenient to adjust. Utility Model Content

[0008] The purpose of this utility model is to solve the shortcomings of the existing technology, which has the disadvantage that the electric arc generated by high voltage can easily pass through the opening of the ventilation plate and damage the partition plate, thus failing to provide protection for the partition plate and facilitate disassembly, replacement and maintenance. Therefore, a ventilation plate for high voltage switchgear is proposed.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A high-voltage switchgear ventilation panel is designed, comprising a partition plate, with snap-fit ​​strips fixed to both sides of the partition plate, snap-fit ​​grooves on the inner side of the snap-fit ​​strips, a protective pad bonded to the outer side of the partition plate, a filter plate installed on the outer side of the protective pad, a ventilation panel installed on the outer side of the filter plate, ventilation holes on the surface of the ventilation panel, and a thermally conductive pad bonded to the outer side of the ventilation panel. A first connecting mechanism connects the upper and lower ends of the ventilation panel, and a second connecting mechanism connects the two sides of the ventilation panel to the two sides of the partition plate. The first connecting mechanism includes a connecting plate, with connecting posts fixed to the inner sides of the upper and lower ends of the ventilation panel, and the connecting plate slidably mounted on the surface of the connecting posts. The second connecting mechanism includes a mounting plate and a clamping plate, with the mounting plate fixed to the outer side of the partition plate and the clamping plate fixed to the inner side of the mounting plate. The sides of the ventilation panel and the thermally conductive pad are inserted between the two clamping plates.

[0011] Furthermore, the surface of the connecting plate has an adjustment groove, the connecting column slides through the adjustment groove, a nut is connected to the surface of the connecting column at the outer end of the adjustment groove, and a first connecting hole is opened at the top of the connecting plate.

[0012] Furthermore, a second connecting hole is provided on the surface of the clamping plate at a position outside the heat-conducting pad, and a tightening bolt is inserted into the second connecting hole, with the inner end of the tightening bolt abutting against the outer edge of the heat-conducting pad.

[0013] Furthermore, the spacer plate is a rectangular structure and is vertically arranged, and both the snap-fit ​​strip and the snap-fit ​​groove are U-shaped structures and are vertically arranged.

[0014] Furthermore, the protective pad is made of insulating and high-temperature resistant rubber, and the filter plate is made of activated carbon and is vertically arranged and slidably inserted into the inside of the snap-fit ​​groove.

[0015] Furthermore, the ventilation plate is a rectangular plate structure, vertically arranged, and has a gap between it and the outer side of the filter plate. The thermal pad is made of thermally conductive silicone material, and the ventilation holes penetrate the surface of the thermal pad.

[0016] Furthermore, the connecting post is a threaded post structure and is horizontally arranged, the adjusting groove is an elongated strip structure, and the first connecting hole is located at the outer end of the adjusting groove.

[0017] Furthermore, the mounting plate is a rectangular plate structure and is vertically arranged, the clamping plate is a rectangular plate structure and is vertically arranged on both sides of the partition plate, and the second connecting hole is a threaded hole structure and is horizontally arranged.

[0018] The ventilation plate for a high-voltage switchgear proposed in this utility model has the following advantages:

[0019] 1. This utility model allows for the detachable installation of ventilation plates on both sides of the partition plate via a second connecting mechanism. Furthermore, the ventilation plates can be conveniently and stably installed via clamping plates and mounting plates. Therefore, installing the partition plate and ventilation plates on both sides within the high-voltage switchgear chamber allows for simultaneous ventilation and heat dissipation of both chambers, improving the internal heat dissipation effect of the high-voltage switchgear. Simultaneously, filter plates and protective pads can be detachably installed on both sides of the partition plate via snap-fit ​​strips and snap-fit ​​grooves. Therefore, electric arcs generated due to high voltage, after passing through the ventilation holes on the surface of the ventilation plate, are separated and protected by the filter plates and protective pads, reducing damage to the partition plate and protecting its safety. Moreover, the partition plate can intercept the electric arc, preventing damage to adjacent high-voltage switchgear chambers. It also facilitates the disassembly, replacement, and maintenance of the partition plate, protective pads, and filter plates. Additionally, the filter plates can absorb moisture from the air passing through the ventilation plates, keeping the air circulating between the high-voltage switchgear chambers dry.

[0020] 2. In this utility model, a connecting plate is detachably installed on the inner side of the upper and lower ends of the ventilation plate via a connecting column. According to the installation connection position inside the high-voltage switchgear cavity, the connecting plate can be rotated or moved through the adjustment groove to adjust the installation position and installation angle of the first connecting hole, so as to correspond to the installation connection position inside the high-voltage switchgear cavity, thereby facilitating flexible installation of the ventilation plate.
