Problems solved by technology

[0005] The disadvantages of this method include that when opening the high-voltage junction box, since the output of the high-voltage power has not been disconnected after opening the box cover and disconnecting the low-voltage connector, between disconnecting the connector and disconnecting the high-voltage power There is a time difference, so there is still a risk of high-voltage electric shock; in addition, when the cover is installed in the box body, the low-voltage connector is located inside the junction box, and maintenance or testing personnel cannot immediately observe the low-voltage connector located inside the high-voltage junction box, so there is The two low-voltage connectors may be staggered and canno

Abstract

The invention relates to an anti-electric shock protection structure for high voltage equipment and the high voltage equipment. A box body of the high voltage equipment is provided with an openable box cover, and the box cover is locked at a closed position by a mechanical connection piece relative to the box body. The anti-electric shock protection structure comprises a low voltage loop and a socket connector, wherein the on-off state of at least one place of a high voltage loop in the high voltage equipment is controlled by a controller through the on-off of the low voltage loop; the socket connector is arranged on the high voltage equipment and shields the mechanical connection piece; the low-voltage loop is conducted through wires arranged in the connector; and when the connector is taken off, the low voltage loop is opened. The above technical scheme has the advantages that electric shock hazard is eliminated, the design, manufacture and use are facilitated, and the cost is effectively reduced.

Description

【Technical field】 [0001] Generally speaking, the present invention relates to the design field of electric shock protection structure of high voltage equipment; more specifically, the present invention relates to an electric shock protection structure and a high voltage equipment with the electric shock protection structure. 【Background technique】 [0002] In many electrical environments, such as electric vehicles, when maintaining or testing high-voltage equipment, it is necessary to first open the high-voltage equipment (such as a high-voltage junction box, etc.). In order to prevent the high-voltage equipment from being opened by maintenance or testing personnel or after the high-voltage equipment is opened, a set of low-voltage connectors that cooperate with each other is generally used as an anti-shock protection device for high-voltage equipment. [0003] Take the high voltage junction box as an example. In the high-voltage junction box of the prior art, the anti-shoc...
