Automatic transfer switch electric appliance for moment parallel device

Abstract

The invention relates to an automatic transfer switching equipment of an instant parallel arrangement, which aims at solving the problem that the existing conversion process of an automatic change-over switch can not realize the aim of uninterruptible power. The electric appliance comprises a latch plate, an oscillating deck A, an oscillating deck B, rollers, a main shaft, a main support, a damper, an electromagnet, a connecting bar which is connected on a movable iron core of the electromagnet and is provided with a slotted hole, a base, a movable contact A, a movable contact B, a fixed contact A and a fixed contact B. Both of the movable contacts are respectively connected to two separate power supplies, both of the fixed contacts are connected on a load terminal, the bottoms of the oscillating deck A and the oscillating deck B are respectively connected with connection blocks which are arranged on the movable iron core on the electromagnet which is arranged on the adjacent side, when the rollers on the two oscillating decks are positioned on the high position of the cam which is arranged on the latch plate, the two movable contacts are instantly and simultaneously connected with the fixing contacts (instantly connected in parallel), which guarantees that at least one of the two power circuits is connected with the loading at any time and the loading can not be interrupted during the changing over process of the switch and realizes the closed switching over of the power source.

Description

technical field [0001] The invention relates to the field of electrical switches, in particular to an automatic transfer switching appliance of an instant parallel device. Background technique [0002] The existing automatic transfer switch on the market adopts two moving contacts and two static contacts. When performing power conversion, one of the moving contacts is disconnected from the static contact first, and the other moving contact is connected to the static contact. The contacts are closed. During the conversion process, two of the moving contacts must be in the open position, and the load will inevitably have a certain power-off time. The power-off time is generally 100ms to 5s, which is satisfactory for general loads. However, for some particularly important places that use electricity, continuous power supply is required, and the conversion of the transfer switch must achieve "zero" switching, without power-off time, and the electrical equipment used can operate...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiency that the existing automatic transfer switch cannot realize continuous power supply during the conversion process, and provides an automatic transfer switch electrical appliance of an instantaneous parallel device, the switch realizes instantaneous parallel connection during the conversion process (two power sources supply power at the same time), standby After the power supply is turned on, the main power supply is disconnected, so as to realize the uninterrupted conversion of the automatic transfer switch
