Problems solved by technology
[0003] However, in the actual use of the prior art, most of the isolating switch structures in the double-column isolating switch adopt the vertical plane folding type, and the isolating switch with the vertical plane folding structure has a large impact on the moving contact and the static contact when closing. , the action stability is poor, which will affect the reliability and stability of the DC isolating switch, which will easily lead to failure of the double-column isolating switch and the electrical appliances connected to the double-column isolating switch

The invention discloses a double-column rotary isolating switch. The switch comprises a supporting seat, one end of the top of the supporting seat is fixedly connected with a left insulating supporting column. The top of one end, away from the left insulating supporting column, of the supporting seat is rotationally connected with a right insulating supporting column; a left wiring contact is fixedly connected to the top of the left insulating supporting column, a right wiring contact is fixedly connected to the top of the right insulating supporting column, a first connecting column is fixedly connected to the top of the left wiring contact, a left metal connecting piece is fixedly connected to the top of the first connecting column, and a contact groove is formed in the middle of the left metal connecting piece. According to the invention, the contact rotates towards the inner wall of the contact groove; the movable rod drives the first piston to move on the inner wall of the fixed sleeve, the first damping spring is matched with the telescopic rod and the second damping spring to play a role in buffering the rotation of the contact, and the contact is prevented from being greatly impacted with the left metal connecting piece and the contact groove when the device is switched on, so that the purpose of higher switching-on action stability is achieved.
Description
technical field [0001] The invention relates to the technical field of isolating switches, in particular to a double-column rotary isolating switch. Background technique [0002] The isolating switch is a switching device that is mainly used to "isolate power supply, switch operation, connect and cut off small current circuits", and has no arc extinguishing function. When the isolating switch is in the off position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; current switching device. It is generally used as a high-voltage disconnector, that is, a disconnector with a rated voltage above 1kV. Its working principle and structure are relatively simple, but due to the large amount of use and high requirements for working reliability, it is very important for the design, establishment and maintenance of substations and power plants. The impact on safe operation is greater. The main feature of the...
