Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage equipment power distribution cabinets, in particular to a sealing structure for high-voltage equipment. Background Art

[0002] A high-voltage power distribution cabinet is a device used to receive high-voltage power supply and distribute it to different electrical equipment or systems. It usually includes components such as circuit breakers, disconnectors, and grounding switches to protect circuits and equipment from power problems such as overloads and short circuits. High-voltage power distribution cabinets are widely used in industry, commerce, and other fields to ensure the safe and reliable operation of power systems.

[0003] In order to ensure the sealing between the distribution cabinet and the sealed door, sealing strips are usually installed in the existing high-voltage distribution cabinet. Due to long-term use and the influence of temperature, the sealing strips are aged, which affects the sealing between the distribution cabinet and the sealed door, so the sealing strips need to be replaced. Since most of the existing sealing strips are directly cast on the surface of the sealed door, the replacement of the sealing strips is more troublesome. In addition, since the distribution cabinet needs to be regularly inspected for safety, the sealed door needs to be opened. Since some sealed doors are connected to the distribution cabinet by screws, the closing of the sealed door will waste a lot of time, thereby affecting the efficiency of the distribution cabinet inspection. In response to the above problems, we have introduced a sealing structure for high-voltage equipment. Utility Model Content

[0029] In the above technical solution, the problem that the sealing strip 7 needs to be replaced due to aging is taken into consideration. In order to solve such a problem, the specific operation is as follows: by manually moving the pressing block 16, the extrusion block 19, the slide rod 18 and the limit block 21 are driven to move, so that the connecting column slides in the first through groove 10, thereby driving the card block 11 to move inside the slide groove 9, so that the card block 11 is disengaged from the card groove 15. At this time, the first spring 12 and the second spring 20 are in a compressed state, and then the sealing strip 7 and the mounting frame 8 are removed. At this time, under the action of the first spring 12 and the second spring 20, the card block 11 will be returned to its original position, and then The new sealing strip 7 and the installation frame 8 are aligned with the notch 26 and placed in. When the corners of the installation frame 8 contact the inclined surface of the block 11, the block 11 will be pushed away. At this time, the first spring 12 and the second spring 20 are in a compressed state. When the slot 15 contacts the block 11, the block 11 re-enters the slot 15 under the action of the first spring 12 and the second spring 20, and then the new sealing strip 7 is fixed again to complete the installation of the sealing strip 7. The operation is simple, convenient and fast. Considering that there will be resistance when pushing the block 11 to move, the pulley 14 can be provided to reduce the resistance and facilitate the movement of the block 11.

[0030] Reference Figure 1 and Figure 7 In a preferred embodiment, the fixing assembly includes a groove 22, which is opened inside the housing 4.

A third spring 24 is arranged on the outer side of the connecting rod 23. One side of the fixing block 5 and one side of the connecting block 6 are both provided with an inclined surface.

[0031] In the above technical scheme, it is considered that some sealed doors are connected to the distribution cabinet by screws, which makes it inconvenient to open the sealed doors. In order to solve such problems, the specific operations are as follows: when it is necessary to open the cabinet door 2, just pull the fixing block 5 by hand to separate the fixing block 5 from the connecting block 6, and then the cabinet door 2 can be opened. When closing the cabinet door 2, when the inclined surface of the connecting block 6 contacts the inclined surface of the fixing block 5, continue to apply force to bounce the fixing block 5 off. At this time, the third spring 24 is in a compressed state. When the cabinet door 2 is completely closed, the fixing block 5 will be offset from the connecting block 6.

When closing the cabinet door 2, when the inclined surface of the connecting block 6 contacts the inclined surface of the fixing block 5, continue to apply force, and the fixing block 5 will pop open. At this time, the third spring 24 is in a compressed state. When the cabinet door 2 is completely closed, the fixing block 5 will be staggered with the connecting block 6. Under the action of the third spring 24, the fixing block 5 is pushed against the connecting block 6, so that the fixing block 5 and the connecting block 6 restrict each other, and then the cabinet door 2 is fixed and closed. When it is necessary to replace the sealing strip 7, the pressing block 16 is manually moved to drive the extrusion block 19, the slide bar 18 and the limit block 21 to move, so that the connecting column slides in the first through groove 10, thereby driving the card block 11 to move inside the slide groove 9, allowing the card block 11 to move from The first spring 12 and the second spring 20 are disengaged from the card slot 15. At this time, the first spring 12 and the second spring 20 are in a compressed state. Then the sealing strip 7 and the installation frame 8 are removed. At this time, under the action of the first spring 12 and the second spring 20, the card block 11 will be returned to its original position, and then the new sealing strip 7 and the installation frame 8 will be aligned with the notch 26 and placed in. When the corners of the installation frame 8 contact the inclined surface of the card block 11, the card block 11 will be pushed away. At this time, the first spring 12 and the second spring 20 are in a compressed state. When the card slot 15 contacts the card block 11, under the action of the first spring 12 and the second spring 20, the card block 11 re-enters the card slot 15, and then the new sealing strip 7 is fixed again to complete the installation of the sealing strip 7. The operation is simple, convenient and quick. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
