Abstract
Provided by the utility model is an adjustable rotating cover plate-based pressure releasing structure for a high-voltage switchgear. The pressure releasing structure comprises a fixed support arranged at an outlet of a pressure releasing channel and a rotating shaft arranged on the fixed support; and one end of a rotatable cover plate is connected with the rotating shaft and the other end thereof is contacted with a friction block arranged at the outlet of the pressure releasing channel. According to the utility model, the provided pressure releasing structure has the following beneficial effects: first, the pressure releasing is realized by rotating the rotating cover plate to open the pressure releasing channel; and thus compared with the existing the pressure releasing structure employing steel plate deformation to realize pressure releasing, the provided pressure releasing structure enables the motion to be carried out reliably; second, the tight degree of the contact between the friction block and the rotating cover plate is adjusted, so that the pressure value enabling the rotating cover plate to be opened under any pressure can be adjusted; third, the provided pressure releasing structure with a compact and simple structure can be used repeatedly; and fourth, the provided pressure releasing structure can be applied to all air insulation and solid insulation switchgears.
Description
Technical field
The utility model relates to a kind of internal pressure releasing structure in the metal enclosed switchgear, is specifically related to a kind of high voltage switchgear with adjustable rotation cover plate pressure relief.
Background technology
Metal enclosed switchgear (hereinafter to be referred as " switch cubicle "), the high pressure elements such as circuit breaker, isolating switch, earthed switch, instrument transformer are equipped with in its inside, and they are disposed in the different compartments, and these compartments have formed complete switchgear jointly.
For the switch cubicle of all electric pressures, its each high pressure compartment will arrange pressure release passage and pressure relief, is used for discharging the pressure in the cabinet under the internal arc fault, protection personal safety and device security.Can how to resolve being designed to of pressure relief safely and discharge smoothly the key of cabinet internal pressure.Existing switch cubicle, the structure of its pressure relief plate are to be out of shape the purpose that reaches earth pressure release by steel plate under internal pressure, but existing pressure release structure for switch cabinet is unreasonable, and pressure release can not be adjusted under which kind of pressure, and Reliability of Microprocessor is poor.
The utility model content
The purpose of this utility model is to provide the adjustable rotation cover plate pressure relief that uses in a kind of high-pressure metal sealing switch equipment.
For achieving the above object, the utility model has adopted following technical scheme:
Comprise being arranged at the fixed support in the pressure release passage outlet and being arranged at rotating shaft on the fixed support, an end of rotating plate links to each other with rotating shaft, the other end be arranged at the brake pad that pressure release passage exports and contact.
Be provided with the pressure adjustment structure that contacts tightness degree for the adjustment brake pad with rotating plate in the described pressure release passage outlet.
Described pressure adjustment structure comprises the adjusting screw(rod) bearing that is arranged in the pressure release passage outlet, is provided with the adjusting screw(rod) that links to each other with brake pad in the adjusting screw(rod) bearing.
High voltage switchgear described in the utility model has following beneficial effect with adjustable rotation cover plate pressure relief:
1. the utility model adopts the mode pressure release of rotating plate rotating opening pressure release passage, comes the pressure relief of pressure release to compare with existing by steel plate deformed, moves more reliable.
2. the utility model is by the contact tightness degree of adjustment brake pad with rotating plate, so that the pressure value capable of regulating that needs rotating plate to open under which kind of pressure.
3. the utility model compact conformation is simple, but Reusability.
4. the utility model is applicable to all air insulations and solid-state insulated switchgear.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the syndeton schematic diagram of pressure adjustment structure described in the utility model and brake pad;
Among the figure: 1. switch cubicle fixed cover plate; 2. rotating plate; 3. fixed support; 4. hold-down screw; 5. rotating shaft; 6. adjusting screw(rod); 7. adjusting screw(rod) bearing; 8. brake pad.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Participate in Fig. 1 and Fig. 2, the utility model comprises and is arranged at the fixed support 3 in the pressure release passage outlet and is arranged at rotating shaft 5 on the fixed support 3, one end of rotating plate 2 links to each other with rotating shaft 5, the other end contacts with brake pad 8 on being arranged at pressure release passage outlet, and brake pad is used for fixedly rotating plate; Be provided with the pressure adjustment structure that contacts tightness degree for adjustment brake pad 8 with rotating plate 2 in the described pressure release passage outlet; Described pressure adjustment structure comprises the adjusting screw(rod) bearing 7 that is arranged in the pressure release passage outlet, is provided with the adjusting screw(rod) 6 that links to each other with brake pad 8 in the adjusting screw(rod) bearing 7.
This pressure relief is comprised of three parts, is respectively fixed support part and rotating plate part and pressure adjustment structure part.Fixed support can be that rotating plate provides support and center of rotation, rotating plate one end is installed on the fixed support and can rotates along rotating shaft, the other end is fixed on the cabinet by one or more pressure adjustment structures, this pressure relief can prevent entering of foreign matter and toy when switch cubicle normally moved, can when rising to a limit value, the cabinet internal pressure be raised by pressure during the switch cubicle arc fault, finish decompression function, pressure adjustment structure can be adjusted the pressure value that need to open within the specific limits.
Embodiment
Rotatable cover plate fixed support is connected on the high-tension switch cabinet fixed cover plate by the fixed support hold-down screw, and its effect is to provide support to rotatable cover plate and rotating shaft; Rotatable cover plate one end is installed in the rotating shaft, and is fixed on the rotatable cover plate fixed support by rotating shaft, and rotatable cover plate can rotate along rotating shaft, and the other end of rotatable cover plate abuts against with brake pad, and fixes by frictional force; The adjusting screw(rod) bearing also is fixedly mounted on the high-tension switch cabinet fixed cover plate, and its effect is to provide support for adjusting screw(rod); But cooperating, adjusting screw(rod) generating horizontal displacement, adjusting screw(rod) and adjusting screw(rod) bearing finish regulatory function; Brake pad is fixedly mounted on the top of adjusting screw(rod) and is close to rotatable cover plate; The pressure release passage outlet is opened in high-tension switch cabinet fixed cover plate.
Before the normal operation of switch cubicle, rotate adjusting screw(rod) and make brake pad and rotatable cover plate be close to and compress.At this moment the movable end of adjusting screw(rod) can be fixed, when switch cubicle moves, can prevent entering of foreign matter and toy.Rotatable cover plate can be when the switch cubicle arc fault and the cabinet internal pressure raised by pressure when rising to a limit value, finish decompression function.Adjustment member can be adjusted the pressure value that need to open within the specific limits.
