Abstract

The invention relates to an automatic transfer switching equipment of the alternating-current/direct-current mixing apparatus, which aims at solving the problem that the switching process of an existing automatic change-over switch can not realize the switching between the alternating current main and the direct current main. The equipment is composed of a bottom board, a master control part, arc-extinguishing equipments A and B, and an input terminal a main shaft, a movable contact, an output terminal and a fixing contact of the alternating-current side,, an input terminal, a main shaft, a movable contact, an output terminal, a fixing contact and an insulating plate of the direct-current side, wherein the master control part, a switch part of the alternating-current and a switch part of the direct-current side are fixed on the bottom board, and the switch parts of the alternating-current side and the direct-current side are separated by an insulation plate. The automatic transfer switching equipment has two sets of independent transfer systems, which can respectively switch on and broke the alternating current main and the direct current main, when one of the common power supply and the stand-by power supply of a user is the direct current power supply and the other is the alternating power supply, the switching between the two power supplies can be realized through using the same change-over switch, and the invention has the advantages the application range is wide, the operation and use is convenient and flexible, and the automatic transfer switching equipment is beneficial for the spread.

Description

technical field [0001] The invention relates to the field of electrical switches, in particular to an automatic transfer switching appliance of an AC / DC hybrid device. Background technique [0002] Existing automatic transfer switching appliances on the market generally have two power supply input terminals and one power supply output terminal. This type of automatic transfer switch can only be used to switch between two power sources of the same nature, that is, an AC switch is used when the two power sources are AC, and a DC switch is used when the two power sources are DC. [0003] In practical applications, there are many places where electricity is used. One of the common power sources and the backup power source is AC power, while the other is DC power. It is necessary to have an automatic transfer switch with an AC-DC hybrid device that can operate on AC power. Converts power to and from DC power. Contents of the invention [0004] The purpose of the present inven...
