Embodiment approach

[0036] method one

[0037] like image 3 As shown, the power source includes a permanent magnet fixed on the first connecting rod 1, and an electromagnetic coil 6 fixedly arranged relative to the shell structure of the load switch. The attraction and repulsion of the permanent magnet and the electromagnetic coil 6 located in the middle.

[0038] Through the above method, the rotation of the first connecting rod 1 can be quickly realized at the moment when the electromagnetic coil 6 is fed with current in different directions, thereby driving the rotation of the second connecting rod 2, so that the arc is cut off quickly, avoiding contact burnout, melting and Phenomena such as bonding, this kind of situation belongs to the situation of built-in power source.

[0039] way two

[0040] The power source includes a gear 7 that is fixedly connected to one end of the two first connecting rods 1 that rotate at a fixed axis, and a double-sided rack 8 that meshes with the two gears 7...

Abstract

The invention relates to electrical products, in particular to a bridge-type contact load switch, comprising two double-link mechanisms arranged symmetrically, each double-link mechanism includes a first link and a second link, the first link One end of the connecting rod rotates on a fixed axis, the other end of the first connecting rod is hinged with the second connecting rod, and the other end of the second connecting rod is hinged with the moving contact. A second connecting rod synchronously drives the moving contact to move in a straight line; the moving contact includes a mounting seat hinged with the two second connecting rods respectively, the mounting seat is provided with a spring sheet, and the spring sheet is arranged relative to the outer ends of the two mounting seats There are two movable contacts, which are respectively arranged corresponding to the two fixed fixed contacts, and also include two guide rails for guiding the two mounting seats. In the present invention, on the one hand, the difficulty of arc starting can be increased from the source, and on the other hand, the contact area between the arc and the air can also be increased, thereby rapidly extinguishing the arc. At the same time, a smart meter is also claimed in the present invention.

Description

technical field [0001] The invention relates to electrical products, in particular to a bridge-type contact load switch and an intelligent electric meter. Background technique [0002] In the prior art, the contact system of the built-in load switch used in the smart meter has two types: single contact or double contact, but both are in the form of moving and static reeds leading out to connect to the load circuit. When this form is applied to In the smart meter, when faced with a large load, the reliability of the smart meter is easily affected due to its limited arc breaking capability. [0003] In view of the foregoing, the present inventor, based on years of rich practical experience and professional knowledge in the engineering application of this type of product, and in conjunction with the application of academic theory, actively researches and innovates, in order to create a bridge contact load switch and smart meter, so that More practical.
