Description

Technical Field

[0001] The utility model relates to the technical field of SVG dustproof boxes, in particular to a dustproof box type SVG device. Background Art

[0002] SVG is a typical power electronic device, which consists of three basic functional modules: detection module, control operation module and compensation output module. Its working principle is that the current information of the external CT detection system is then analyzed by the control chip to obtain the current information, such as PF, S, Q, etc.; then the controller gives the compensation drive signal, and finally the inverter circuit composed of the power electronic inverter circuit sends out the compensation current. When the SVG device is used outdoors, in order to ensure the normal use of the SVG device, it is necessary to ensure that the SVG device has a certain dustproof performance.

[0003] The dustproof box type SVG generally refers to a device with a dustproof box outside. The SVG is installed inside the box. Through the heat exchange mode, it ensures the internal air is clean while exporting the heat from the device to ensure the normal operation of the device.

[0004] However, in the prior art, the internal space is isolated from the external space by a box body for dust prevention, and the air-cooling component of the external heat exchange mechanism is also provided with a dustproof net. Dust will gradually accumulate on the dustproof net surface due to long-term use, resulting in a decrease in the heat dissipation efficiency of the heat exchange component. Regular cleaning is required, otherwise the heat of the heat exchange component cannot be discharged in time, and the SVG temperature in the internal space of the box body will increase, resulting in operational failures. Therefore, the dustproof box-type SVG structure needs to be cleaned of dust regularly, otherwise it will be difficult to ensure normal heat dissipation operation, and actual use will incur additional labor costs and large maintenance costs. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a dustproof box-type SVG device to solve the background technical problems.

[0006] To achieve the above purpose, the utility model adopts the following technical solution.

[0010] As a further description of the above technical solution: the bottom end of the air guide duct extends to the bottom of the inner side of the cabinet, and the bottom end of the air guide duct is fixedly connected with an equal flow outlet.

[0011] As a further description of the above technical solution: the top and the bottom of the hollow heat conducting plate are both provided with two rows of heat dissipating fins arranged at equal distances.

[0012] As a further description of the above technical solution: an inspection door is hinged on the front of the cabinet, and a sealing gasket is arranged on the outer side of the inspection door.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] This solution realizes air circulation in the space inside the cabinet through the inner isolation cover and the first fan.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] See also Figures 1 to 4 In the utility model, a dustproof box-type SVG device includes a cabinet 1, an SVG main body 2 is fixedly installed inside the cabinet 1, an inner isolation cover 3 is fixedly installed inside the cabinet 1, hollow heat conducting plates 4 arranged at equal distances are plugged into the top of the cabinet 1, the bottom ends of the hollow heat conducting plates 4 are plugged into the inside of the inner isolation cover 3, a first fan 7 is installed on the back of the inner isolation cover 3, an air duct 5 is fixedly installed at the bottom of the front of the inner isolation cover 3, a variable wind direction dustproof mechanism 6 is installed on the top of the cabinet 1, and the top ends of the hollow heat conducting plates 4 are plugged into the inside of the variable wind direction dustproof mechanism 6.

[0023] In the utility model, the cabinet 1 is used as the external protective enclosure of the SVG main body 2, so that the SVG main body 2, when the SVG main body 2 is running, starts the first fan 7 on the back of the inner isolation cover 3, so that the air in the internal space of the cabinet 1 is circulated, and when passing through the inner isolation cover 3, the hollow heat conduction plate 4 absorbs the heat of the high-temperature air and guides it to the inside of the variable wind direction dustproof mechanism 6, and the variable wind direction dustproof mechanism 6 is started to drive the external air to efficiently export the heat of the internal hollow heat conduction plate 4, thereby achieving the advantage that the device can not only effectively isolate and dustproof the working space of the SVG main body 2, but also ensure the stable heat dissipation effect of the device, and reduce the cost of manual cleaning and maintenance, and solve the problem that the dustproof box-type SVG structure in the prior art needs to clean dust regularly, otherwise it will be difficult to ensure normal heat dissipation operation, and actual use will generate additional labor costs and large maintenance costs.
