Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] Figure 1 to Figure 13 As shown, a transfer switch includes a base 1, on which two sets of contact mechanisms 2 and two sets of reversing mechanisms 3 are installed, and each set of reversing mechanisms 3 drives a set of contact mechanisms 2 to realize opening and closing. A set of contact mechanism 2 makes the load terminal 4 and the common power supply terminal 5 open and close, and another set of contact mechanisms 2 makes the load terminal 4 and the backup power supply terminal 6 open and close. Each set of reversing mechanism 3 includes An operating rotating shaft 31 on the seat 1, an electromagnetic coil 32 fixed on the base 1, the operating rotating shaft 31 is used to drive the contact mechanism to open and close, and the middle part of the operating rotating shaft 31 is fixedly connected to a reversing plate 33, and th...

Abstract

The invention discloses a change-over switch, which comprises a base, wherein the base is provided with two groups of contact mechanisms and two sets of reversing mechanisms; each set of reversing mechanism drives one group of contact mechanisms to achieve opening and closing; each set of reversing mechanism comprises an operation rotating shaft, an electromagnetic coil, a reset pressure spring, a movable iron core, a reversing plate, a limiting rod, a linkage part, a drive pin, a connecting pin and a first tension spring; each reversing plate is provided with a guide positioning hole or a guide positioning groove; two guide bevel edges and two positioning grooves are arranged in the inner side surface of each guide positioning hole or guide positioning groove; two guide bevel edges are distributed in a splayed form; one end of each drive pin is inserted into the corresponding guide positioning hole or guide positioning groove; when the electromagnetic coils are energized, the corresponding operation rotating shafts drive the corresponding contact mechanisms to open and close; when the electromagnetic coils are de-energized, the reset pressure springs drive the corresponding movable iron cores to reset; and the first tension springs drive the corresponding drive pins to be matched in the corresponding positioning grooves to position the corresponding reversing plates and operation rotating shafts. The change-over switch is compact in structure, relatively small in volume and relatively high in action reliability.

Description

technical field [0001] The invention relates to the technical field of transfer switch manufacturing. Background technique [0002] A transfer switch is a switching device that can be used for two or more power sources or load conversions. Transfer switches are widely used in various places that require uninterrupted power supply, which realizes the conversion of load lines between two power sources to ensure the reliability of power supply for users. [0003] In 2010, an invention patent with the patent number ZL200810005018.5 and the name "Continuous Dual Power Transfer Switch" was published, which includes the housing, contact opening and closing system and mechanical transmission system; its structural features are: this kind of non-interruptible The dual power transfer switch includes two mutually independent mechanical transmission systems and two mutually independent contact opening and closing systems, and each mechanical transmission system drives a contact opening...
