PC-class automatic changeover switch device with energy storage mechanism

Abstract

The invention relates to a PC-class automatic changeover switch device with an energy storage mechanism. The device comprises a base, a contact system which is arranged on the base, the energy storage mechanism which is in transmission connection with the contact system and a drive motor which is in transmission connection with the energy storage mechanism, wherein the drive motor is fixed on the base through a motor support; the energy storage mechanism comprises an energy storage support unit, an energy storage gear, an energy storage handle, an energy storage spring assembly and an energy storage cam, wherein the energy storage support unit is fixedly connected to the motor support; the energy storage gear is arranged in the energy storage support unit and is in transmission connection with the drive motor; the energy storage handle which is arranged above the energy storage gear and the bottom of the energy storage handle which is engaged with the energy storage gear; the energy storage spring assembly cooperates with the energy storage gear; and the energy storage cam is coaxial to the energy storage gear, is arranged at the outer side of the energy storage support unit and is in transmission connection with the contact system. Compared with the prior art, the device has simple and compact overall structure and convenient processing and manufacturing, and the energy storage mechanism is provided, so that when the automatic changeover switch rotates, the phenomenon of clamping stagnation or failed linkage cannot occur, and the device is safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of electrical switches, and relates to a PC-level automatic transfer switch device with an energy storage mechanism. Background technique [0002] As we all know, automatic transfer switching equipment, namely ATSE (Automatic Transfer Switching Equipment), is mainly suitable for emergency power supply systems with rated voltage AC not exceeding 1000V or DC not exceeding 1500V, and interrupting power supply to the load during power conversion. ATSE can be divided into two levels: PC level and CB level. Among them, PC level ATSE only completes the function of automatic conversion of dual power supplies, and does not have the function of short-circuit current breaking (only able to connect and carry); CB level ATSE both completes dual power supply. It has the function of automatic power conversion and short-circuit current protection (can be switched on and off). [0003] At present, part of the PC-level autom...

Problems solved by technology

When the product is connected and disconnected, the mechanism cannot quickly connect and disconnect the contacts, resulting in very low connection and disconnection and electrical life of the product, which is not conducive to improving the use category and electrical life of the product

Once the circuit generates a large current, the product will burn out when it is turned on and off, causing power consumption problems such as power supply interruption, resulting in losses
