Description
Technical Field
[0001] The utility model relates to the technical field of isolating switches, in particular to an outdoor high-voltage AC isolating switch. Background Art
[0002] An isolating switch is a switching device mainly used for "isolating power supply, switching operation, and connecting and disconnecting low-current circuits". When the isolating switch is in the open position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; when it is in the closed position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time.
[0003] The isolating switch consists of a first insulating support, a second insulating support, and a knife plate arranged between the first insulating support and the second insulating support, which can perform opening and closing. There is a connector on the first insulating support that contacts the knife plate. During the connection process, when the distance between the two sides of the knife plate is too large, the resistance will increase, thereby reducing the current passing through the knife plate. When the distance between the two sides of the knife plate is too large, it will make closing difficult. Utility Model Content
[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that when the distance between the two sides of the blade is too large or too small, it will affect the operating quality of the isolating switch during use, thereby providing an outdoor high-voltage AC isolating switch that can adjust the distance between the two sides of the blade.
[0005] To this end, the utility model provides an outdoor high-voltage AC disconnector, comprising a first insulating support, a second insulating support and a blade plate arranged therebetween, the blade plate being sleeved with a connecting rod and a baffle rod, the first insulating support being provided with a connector plate, the blade plate having a closed state in which the baffle rod is in contact with the connector plate and an open state in which the baffle rod is separated from the connector plate, an elastic member in an extruded state and an adjusting member for adjusting the distance from the elastic member to the blade plate being provided at the extension of the connecting rod, a positioning member for fixing the position of the adjusting member being connected to the side of the adjusting member, the elastic member being sleeved on the outer end face of the connecting rod and being located between the blade plate and the positioning member.
[0006] Further: the knife plate includes a first conductive plate and a second conductive plate arranged opposite to each other, the connector plate is located between the first conductive plate and the second conductive plate, the extended position of the connecting rod has an external thread, and the adjusting member is provided with an internal thread adapted to the external thread, the adjusting member includes a first compression spring cover and a second compression spring cover arranged opposite to each other, the first compression spring cover and the second compression spring cover are both sleeved on the outside of the connecting rod, and the first compression spring cover conflicts with the side wall of the first conductive plate or the second conductive plate.
[0007] Furthermore: one side of the first compression spring cover is in contact with the side wall of the first conductive plate, and the other side is provided with a first limiting groove for the elastic member to be inserted into. The second compression spring cover is provided with a second limiting groove on the side opposite to the first compression spring cover, and the other side can be against the positioning member, and the two ends of the elastic member are respectively inserted between the first limiting groove and the second limiting groove.
[0008] Furthermore: the elastic member and the adjusting member are wrapped with a protective cover.
[0009] Furthermore: the protective cover includes a protective shell and a protective cover arranged on the side of the protective shell, and the protective cover is wrapped around the outside of the protective shell.
[0010] Furthermore: the elastic member is a spring.
[0011] The technical solution of this utility model has the following advantages:
[0012] 1. The utility model provides an outdoor high-voltage AC disconnect switch, in which an elastic member, an adjusting member and a positioning member are provided on the side of the blade plate, the elastic member is provided in the middle of the adjusting member, and then the squeezing force of the elastic member on the side of the blade plate is controlled by the positioning position of the positioning member. When the positioning member is closer to the side of the blade plate, the squeezing force of the elastic member on the blade plate is stronger. When the blade plate is in the process of closing, the connector plate will be stuck in the inside of the blade plate and squeeze the inner wall of the blade plate. When the connector plate squeezes the side wall of the blade plate, the force on the side wall of the blade plate will act on the elastic member, squeezing the elastic member to generate a deformation force. When the blade plate is fully closed, the elastic member will have a squeezing force on the side wall of the blade plate due to its own elastic deformation force, which can ensure that the connector plate is in contact with the inner wall of the blade plate, and will not make the distance between the connector plate and the inner wall of the blade plate too narrow, resulting in difficulty in closing.
[0013] 2. The utility model provides an outdoor high-voltage AC disconnect switch, wherein a blade plate includes a first conductive plate and a second conductive plate arranged opposite to each other, and when the blade plate is closed, both sides of the connector plate will contact the inner side walls of the first conductive plate and the second conductive plate respectively, and an external thread is provided on the extension of the connecting rod. During the processing, the first compression spring cover can be inserted first, and then the elastic member is inserted, and then the second compression spring cover is inserted, so that the two ends of the elastic member are respectively stuck in the first limit groove and the second limit groove, and finally the positioning member is screwed in, and the position of the fixing member is determined through multiple tests (the position of the fixing member is continuously adjusted during the test to adjust the force of the elastic member on the first conductive plate, so as to find a position that can avoid difficulty in closing and avoid excessive distance between the first conductive plate and the second conductive plate, thereby causing excessive resistance). After the position is determined, the positioning member is screwed in. The threaded arrangement of the positioning member and the connecting rod can facilitate the adjustment of the position of the positioning member during use. BRIEF DESCRIPTION OF THE DRAWINGS
