Embodiment Construction
[0031] The present invention will be described below in conjunction with the accompanying drawings in the application of a pair of transfer switch electrical linkages. Throughout the description, the same components use the same reference numerals. Many components are the same for both transfer switch devices, or for the interlocks connected to the corresponding transfer switch devices. In this case, the same reference numerals are used for the same components in the two transfer switch devices or corresponding interlocking devices, and then the suffix "a" or "b" is used to distinguish them after the reference numerals.
[0032] refer to figure 1 as shown, figure 1 Disclosed is a structural diagram of an interlocking device for a transfer switch appliance according to an embodiment of the present invention. A pair of transfer switch electrical appliances includes a first transfer switch appliance 1a and a second transfer switch appliance 1b. exist figure 1 In the illustrat...

The invention provides a drive piece of an interlocking device of a change-over switch electric appliance. The drive piece comprises a support structure, a driven shaft, a driven lever and a bias spring. The driven shaft penetrates through the support structure. The driven lever is installed at the end, located on the outer side of the support structure, of the driven shaft, the middle portion of the driven lever is connected to the driven shaft, and the driven lever can rotate around the driven shaft. One end of the bias spring is connected to one end of the driven lever, the other end of the bias spring is connected to the upper edge or the lower edge of the support structure, and the bias spring enables the driven lever to be arranged clockwise or anticlockwise in a bias mode. A connector or a sliding block is arranged at the end portion of the driven lever. The invention further provides the interlocking device of the change-over switch electric appliance. The interlocking device is composed of two drive pieces and a connecting rod. One end of the connecting rod can be connected with the connector, a sliding groove is formed in the other end of the connecting rod, and a sliding block is embedded into the sliding groove and can slide in the sliding groove.
Description
technical field [0001] The invention relates to the field of low-voltage electrical appliances, more specifically, to a transfer switch electrical appliance and an interlocking mechanism thereof. Background technique [0002] In many important power supply occasions, it is necessary to use two power sources for power supply, such as airports, docks, hospitals, etc. In order to ensure the safe and reliable operation of the load, it is necessary to install a transfer switch (ATSE) to complete the conversion between power sources to meet the continuity of the power supply system . ATSE has a common power side and a backup power side. The operating mechanism (also known as the driving mechanism) is an important part of the ATSE, and it is a mechanical transmission structure that completes the switching between the normal side and the standby side power supply. [0003] In existing products, although ATSE can realize the conversion between two power sources to meet the stabilit...
