Description

Technical Field

[0001] The utility model relates to the technical field of transformer substations, in particular to an outdoor box-type transformer substation. Background Art

[0002] Box-type substation, also known as prefabricated substation or prefabricated substation, is a kind of high-voltage switchgear, distribution transformer and low-voltage distribution device, which are prefabricated indoor and outdoor compact distribution equipment arranged in one according to a certain wiring scheme, that is, the transformer step-down, low-voltage distribution and other functions are organically combined together, and installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box, which is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after the civil substation. The box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil distribution room and distribution station and becomes a new type of complete set of transformer and distribution equipment.

[0003] For example, an outdoor box-type substation disclosed in Chinese patent announcement No. CN219611181U belongs to the technical field of substations. The outdoor box-type substation includes a cabinet, and No. 1 cabinet doors are rotatably installed on both sides of the front surface of the cabinet, and a self-cleaning filter assembly is fixedly installed on one side surface of each No. 1 cabinet door, and a No. 2 cabinet door is rotatably installed on the front surface of the cabinet between the No. 1 cabinet doors on both sides, and a heat-insulating and waterproof box top is fixedly installed on the upper surface of the cabinet, and a transformer unit is fixedly installed on the inner wall of the bottom of the cabinet. The self-cleaning filter assembly can prevent dust or insects from entering the transformer box, thereby reducing the working efficiency of the transformer box or causing equipment failure, and the filter can be automatically cleaned to maintain normal ventilation and heat dissipation in the cabinet, thereby ensuring the normal operation of the equipment, improving the operation efficiency of the transformer box, and extending the period requiring personnel maintenance, providing a certain convenience in use.

[0004] However, as in the above patent, there is still a problem of poor cleaning and dust collection effect on the filter. For example, in the above patent, a mechanically driven cleaning component is set to sweep and clean the surface of the filter to avoid dust accumulation in the filter that affects the heat dissipation effect, and the cleaning structure collects dust through a dust box placed at the bottom. However, in this process, the dust needs to fall into the dust box to be collected, and the dust cleaning is dynamic, which will cause the accumulated dust to be broken up again to form dust. The dust is not easy to fall and will float in the substation box, which is easy to affect the normal operation of electrical components in the substation. Utility Model Content

[0028] The working principle of the above embodiment is:

[0029] (1) When the ventilation filter in the substation is used to improve the cleaning effect, the controller sends a signal to the drive motor 34, and the motor starts to rotate. The output shaft drives the screw rod 33 fixedly connected to it to rotate. The rotation of the screw rod 33 is connected to the movable plate 35 through a thread, so that the movable plate 35 moves linearly along the screw rod 33. The movement of the movable plate 35 drives the cleaning brush 38 fixedly connected to it to move. The slide grooves on the front and rear sides of the movable plate 35 cooperate with the slide rails 310 on the ventilation frame 31 to ensure that the movable plate 35 can slide smoothly on the slide rails 310. The cleaning brush 38 moves to the position of the filter plate 32 and starts to clean the dust on the filter. The vibration motor 39 is started at the same time to provide additional vibration force to help the brush remove dust more effectively. The support spring 37 provides support and elasticity for the cleaning brush 38 to ensure that the brush is in contact with the filter plate 32. At the same time, the brush is allowed to have a certain elasticity to adapt to the irregularities on the surface of the filter plate 32. The cleaned dust falls into the collection cover 36 and is further processed by the dust collection mechanism 4.

[0030] (2) When the cleaned dust is collected for use, the rotating shaft 43 and the dust suction fan blades 44 are driven by the servo motor 45 to form suction, and the dust is sucked into the dust box 46 from the collection cover 36 through the dust collection hose 41. The dust box 46 is used to temporarily store the collected dust. The collection frame 47 is placed on the inner bottom wall of the dust box 46 to collect dust and facilitate cleaning and replacement. A dustproof net is fixed to the inner wall of the exhaust duct 48 to exhaust air and prevent dust from escaping. The box door is hinged by a hinged frame, which is convenient for maintenance personnel to check and clean the dust box 46.
