Problems solved by technology

[0003] 10kv switchgear is widely used in the power industry. It has good switching effect and insulation effect, and has good safety and ease of operation. However, there are also many problems in the existing 10kv switchgear. Among them, the most problematic Obviously, the cleaning problem in the cabinet, the existing 10kv switchgear must be stopped for cleaning, which will affect the normal production, and at the same time, the opening and closing of the 10kv switchgear due to the cleaning work will affect the service life of its circuit breaker , reducing the safety of the switchgear. In addition, if the cabinet is not cleaned in time, it may affect the insulation of the switchgear and endanger the safety of people or equipment.

specific Embodiment 1

[0038] like figure 1 , a high-efficiency dust removal 10kv switch cabinet of the present invention includes a cabinet body, and a dust removal mechanism is provided on the cabinet body. The dust removal mechanism includes a gas storage tank 1, a purification mechanism 4, a decompression mechanism 2, a booster mechanism 5, and a heat exchanger 6 , air injection mechanism 7, exhaust mechanism 3, gas storage tank 1 is connected to the air injection mechanism 7 located in the cabinet through heat exchanger 6, decompression mechanism 2 successively, the cabinet is provided with exhaust mechanism 3, exhaust mechanism 3 through the purification mechanism 4, the heat exchanger 6, and the pressurization mechanism 5 in order to connect back to the gas storage tank 1, and the gas storage tank 1 is filled with inert gas.

[0039] The purification mechanism 4 includes a vacuum cleaner, a humidity controller, and an electroparticle adsorber connected in sequence; the output end of the elect...

specific Embodiment 2

[0047] According to the control system of the switchgear of embodiment 1, comprise:

[0048] (1), control unit;

[0049] (2) The purification unit includes a vacuum cleaner, a humidity controller, and an electric particle adsorber. The dust suction net in the vacuum cleaner filters the airflow; the filtered airflow enters the humidity controller, and the humidity controller includes a sponge net and an extruded plate. The sponge net has a number of curved through holes with a diameter not greater than 3cm and a length greater than 10cm. Activated carbon with a particle size of less than 5 mesh is arranged on the inner wall of the through hole. The sponge net absorbs the moisture in the airflow and filters the airflow again; Embosses are arranged horizontally on the pressing plate, the height of the embossing is 3-5mm, and the spacing of the embossing is 5-8mm. The extruding plate is connected with an extruder, and the extruder controls the extruding plate to extrude the sponge...

specific Embodiment 3

[0058] Injection method according to the control system of embodiment 2:

[0059] (1), the control unit controls the rotation of the motor installed on the spray seat, the spray head rotates around the spray seat, the average speed of its rotation is 20r / min, the spray head rotates non-uniformly, and the rotation speed of the spray head when it is downward is 16r / min, the rotation speed of the spray head is 24r / min when it is upward;

[0060] (2) The control unit controls the reciprocating movement of the injection seat on the spiral slide rail. The control unit controls the movement speed of the injection seat. When the injection seat is above the center point of the slide rail, its moving line speed is 1-2m / min. The moving line speed is 2-3m / min when it is lower than the center point of the slide rail;

[0061] (3) When the control unit controls the wind pressure at the spray head to be lower than 1kpa, the moving speed of the spray seat on the slide rail is 0m / min, and the...

Abstract

The invention relates to a 10kV switchgear cabinet capable of being dedusted highly efficiently. The 10kV switchgear cabinet comprises a cabinet body and is characterized in that the cabinet is provided with a dedusting mechanism. The 10kV switchgear cabinet has beneficial effects of being simple in structure, convenient to use, easy to popularize, and suitable for the inner chamber structures of various types of switchgear cabinets, and having a good dedusting effect. Each part in the switchgear cabinet can be blown omnibearingly in order to reduce dedusting dead angles and enhance the dedusting of the top surface and the side surface of each element. The 10kV switchgear cabinet achieves an ideal dedusting way, may centralize much dedusting power consumption on the top surface and the side surface, with much dust, of each element, and reduces energy consumption.

Description

technical field [0001] The invention relates to a 10kv switchgear with high-efficiency dust removal. Background technique [0002] 10kv switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. 10kv switchgear is used as an electrical product with a voltage level of 3.6kV-550kV, and a high-voltage isolating switch. And earthing switch, high-voltage load switch, high-voltage recloser and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and 10kv switchgear and other major categories. [0003] 10kv switchgear is widely used in the power industry. It has good switching effect and insulation effect, and has good safety and ease of operation. However, there are also many problems in the existing 10kv switchgear. Among them, the most problematic Obviously, the cleaning problem in the cabinet, the existing 10kv switchgear must b...
