Problems solved by technology

For example, at the mechanism level, the forward and reverse rotation of the motor is used to simulate manual opening. The driving device is a motor, and its own opening time reaches 0.5 seconds, which does not meet the requirements for fast breaking, and is not suitable for remote operation.
In addition, the contact poles are extinguished by adding arc extinguishing chambers

Embodiment Construction

[0050] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but it should not be understood that the protection scope of the present invention is limited to the following embodiments.

[0051] 1 product machine

[0052] see figure 1 , and also see figure 2 and Figure 13 , showing the overall structure of the isolating switch product of the present invention. like figure 1 As shown, the isolating switch includes a mechanism pole 100 and a contact pole 200 , wherein the mechanism stage 100 is provided with an opening and closing device 100 a for driving the contact mechanism 200 a of the contact pole 200 . Among them, the opening and closing operation can be carried out manually or automatically: when it is manual, it is realized by rotating the main shaft through the knob 101; when it is automatic, it is realized by directly driving the opening and closing parts, and the opening action can ...

Abstract

The invention discloses a disconnecting switch and a contact mechanism thereof. The contact mechanism comprises a contact pole seat body, a moving contact seat, a moving contact and a static contact, the static contact is fixedly installed on the contact pole seat body, the moving contact seat is rotatably supported on the contact pole seat body, the moving contact is fixedly installed on the moving contact seat, the moving contact seat is provided with an upper seat disc and a lower seat disc, and a gas pushing block is arranged between the upper seat disc and the lower seat disc and extends from the center of the moving contact seat to the edge of the moving contact seat, so that the gas pushing block forms a cavity with the gas channel walls of the upper seat disc, the lower seat disc and the contact electrode seat body when the moving contact is in a closed position, and the gas pushing block pushes gas to flow in the gas channel of the disconnecting switch when the moving contact rotates. The performance of the disconnecting switch product can be improved.

Description

technical field [0001] The present invention relates to the technical field of electrical equipment, in particular to an isolating switch and its mechanism and components, and more particularly to an isolating switch and its contact mechanism. Background technique [0002] Photovoltaic inverters usually need to be equipped with a rotary isolation switch, which has a contact pole and a mechanism pole. The contact stage is composed of multiple sets of coaxial moving contacts and static contacts, which are connected to the corresponding The terminal, the mechanism level is driven by the rotation of the contact to clutch with the static contact, so as to realize the closing and opening of the circuit system. [0003] At present, with the development of economy and society, the application scenarios of isolation switches are becoming more and more extensive, and the performance is getting better and better, but there are still shortcomings. For example, the mechanism level adopt...
