Double-energy storage operating mechanism of single operating shaft

Abstract

The invention discloses a double-energy storage operating mechanism of a single operating shaft, which is used for automatic transfer switching equipment and comprises an operating handle or an operating motor, a transmission gear and energy storage mechanisms, wherein the operating handle or the operating motor is positioned at the first side of an installation plate of an operating mechanism of the automatic transfer switching equipment and is sheathed in a first operating cam main shaft of the operating mechanism, and the first operating cam main shaft is driven to rotate by the operating handle and operating motor; the transmission gear is positioned at the second side of the operating mechanism and is connected with the first operating cam main shaft and a second operating cam main shaft of the operating mechanism, and the second operating cam main shaft is driven to rotate by the rotation of the first operating cam main shaft through the transmission gear; and the energy storage mechanisms are connected to the first operating cam main shaft through a first cam, are also connected to the second operating cam main shaft through a second cam, and are respectively driven to store energy by the rotation of the first operating cam main shaft and the second operating cam main shaft through the first cam and the second cam.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, and more specifically relates to a double energy storage operating mechanism with a single operating shaft. Background technique [0002] Automatic transfer switching equipment (ATSE for short) is mainly used for switching between two power sources. ATSE can be divided into PC level and CB level. PC level ATSE is an ATSE that can be connected and carried, but not used to break short-circuit current. CB level ATSE is equipped with an overcurrent release ATSE, and its main contacts can be connected and used To break the short-circuit current. In Europe, ATSEs with a rated current above 630A only use CB grades, and in North America, ATSEs only use PC grades. In China, the ATSE standard is equivalent to the IEC standard, and both PC level and CB level can be used. [0003] CB-level ATSE is composed of two circuit breakers, electric operating mechanism, mechanical-electrical interlo...

AI Technical Summary

Problems solved by technology

The split mechanism is more complex and has low reliability; it cannot ensure the reliable operation of fire-fighting equipment

CB-level ATSE has the possibility that the circuit breaker will trip due to overcurrent in some cases, resulting in the possibility that the ATSE will not switch, and the backup power supply cannot be supplied to the load.

Larger size and lower reliability

[0004] At present, there is a CB-level integrated ATSE product on the market, which uses two sets of operating mechanisms, no motor energy storage, large volume, and cannot be used for PC-level protection.
