A bypass circuit of an automatic transfer switch

Abstract

The invention relates to a bypass loop of an automatic diverter switch. The bypass loop comprises a base and a bypass loop device. The bypass loop device comprises an operating mechanism, a connecting rod and three buses. One ends of the three buses are respectively fixed to the base and the three buses are arranged side by side. The second bus is located between the first bus and the third bus, the other end of the first bus, the other end of the second bus and the other end of the third bus are provided with a frequently-used power supply connecting end, a load connecting end and a standby power supply connecting end respectively, the middle of the first bus and the middle of the third bus are provided with contacts, one end of the connecting rod is fixed to the operating mechanism, the other end of the connecting rod is fixedly provided with a disconnecting link, the disconnecting link is connected to the middle of the second bus through soft connecting, and the disconnecting link can be communicated with the contacts in the middle of the first bus and the middle of the third bus along with the upward action and the downward action of the connecting rod fixed to the operating mechanism respectively. The bypass loop has the advantages that the structure is simple, the power supply reliability is high, and it can be well guaranteed that when an automatic diverter switching appliance body needs to be overhauled and maintained, electricity can be supplied to equipment constantly.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical appliances, and in particular relates to a bypass circuit of an automatic transfer switch electrical appliance. Background technique [0002] The most important thing for the automatic transfer switch is to ensure the reliability of the power consumption of important electrical equipment. Setting a bypass circuit on the automatic transfer switch can improve the reliability of the power supply of the automatic transfer switch, and can better ensure the power supply of the transfer switch itself. It is necessary to provide uninterrupted power supply to important equipment during repair and maintenance. However, the existing two types of automatic transfer switching appliances are not provided with a bypass circuit, and the reliability of their power supply is not ideal. [0003] One is the traditional 630A or above automatic transfer switch electrical appliance, which uses a double-m...

AI Technical Summary

Problems solved by technology

The automatic transfer switch has a complex structure and a large footprint, which is not economical and a source of waste

[0005] Using the above two dual power supply switching methods, although the effect of switching can be achieved, there are still shortcomings such as long switching time and obvious power failure time during the switching process.

There is a long power outage time in the process of overhaul and maintenance
