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

[0053] like figure 1 , a 10kv switchgear with electrostatic precipitator of the present invention comprises a cabinet body on which a dust removal mechanism is provided, and 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.

[0054] The purification mechanism 4 includes a vacuum cleaner, a humidity controller, and an electroparticle adsorber connected in sequence; the output end of the electroparticle ad...

specific Embodiment 2

[0062] According to the control system of the switchgear of embodiment 1, comprise:

[0063] (1), control unit;

[0064] (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

[0073] According to the control method of the control system of embodiment 2:

[0074] (1) After the control unit is started, the control system starts the fan, air compressor, and pressure reducing valve in sequence;

[0075] (2) After the airflow with cabinet dust enters the purification unit through the exhaust unit, it first enters the inlet of the vacuum cleaner. After the pleated dust net in the vacuum cleaner absorbs and filters the visible dust in the airflow, the airflow passes through the vacuum cleaner. The outlet is output, and the airflow is filtered for the first time on the vacuum net;

[0076] (3) The airflow output from the outlet of the vacuum cleaner enters the humidity controller, and the airflow is shunted in the humidity controller. The shunted airflow passes through the through holes on the sponge net respectively, and the moisture in the airflow is absorbed by the sponge. Odor or some particles are adsorbed by the activated carbon in the through hole, ...

Abstract

The invention relates to a 10 kv switch cabinet realizing live-line dedusting. The switch cabinet comprises a cabinet body. The cabinet body is provided with a dedusting mechanism. The switch cabinet is simple in structure, convenient to use, convenient to popularize, applicable to all cabinet inner cavity structures of various kinds of switch cabinets and good in dedusting effect. A control system of the dedusting mechanism is reasonable in matching, tacit in cooperation, unified in control and capable of uniformly and cooperatively completing dedusting, spraying, cleaning and gas exhausting. Air more suitable for dedusting is provided by a cleaning method, a supercharging method and a spraying method enable dedusting air to form air flows, a better deducting effect is achieved, and dust absorbed on parts is removed. The dedusting mechanism is suitable for live-line dedusting of the cabinet switch, and the switching frequency caused by dedusting is lowered, so that the service lifetime of the switch cabinet is prolonged, and dust is prevented from accumulating in the cabinet and further reducing the insulating property or influencing normal work of elements.

Description
