Problems solved by technology

For example, in the DC system, the rated operating voltage of low-voltage electrical appliances can be as high as 1000V. For this, many manufacturers at home and abroad have introduced various circuit breaker wiring application schemes. Where it's good enough, its structure is in dire need of improvement

Abstract

The invention discloses an automatic mine switch. The automatic mine switch comprises a plastic base, a plastic upper cover, a wiring assembly, a contact system, an operation mechanism, an arc extinction mechanism and a trip device, wherein the wiring assembly, the contact system, the operation mechanism, the arc extinction mechanism and the trip device are arranged on the base. The contact system comprises three fixed contacts and three moving contacts. The operation mechanism drives the three moving contacts to achieve synchronous switch-on-off movements. The arc extinction mechanism comprises three arc extinction covers which are matched with the three moving contacts. The wiring assembly comprises a first wire inlet terminal connected with the first fixed contact, a second wire inlet terminal connected with the second fixed contact, a third wire inlet terminal connected with the third fixed contact, a first wire outlet terminal connected with the first moving contact, a second wire outlet terminal connected with the second moving contact, and a third wire outlet terminal connected with the third moving contact. The first wire outlet terminal is in short circuit connection with the second wire outlet terminal, and the second wire inlet terminal is in short circuit connection with the third wire inlet terminal. Compared with a traditional product, the automatic mine switch greatly improves grades of rated working voltage and current.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical appliances, and in particular relates to an automatic mine switch. Background technique [0002] With the development of the times, higher requirements have been put forward for low-voltage electrical components used in mines. For example, in the DC system, the rated operating voltage of low-voltage electrical appliances can be as high as 1000V. For this, many manufacturers at home and abroad have introduced various circuit breaker wiring application schemes. Where it is desirable, its structure is in dire need of improvement. Contents of the invention [0003] The object of the present invention is to provide a mining automatic switch with simplified structure, simple operation and high current on-off. [0004] The technical solution for realizing the purpose of the present invention is: a mining automatic switch, including a plastic base, a plastic upper cover, a wiring assemb...
