Problems solved by technology

[0003] At present, the existing manual maintenance switch has the following disadvantages: 1. The fuse is usually non-removable. If the fuse is broken, the entire manual maintenance switch will be scrapped, wasting resources and increasing costs; 2. The existing manual maintenance switch , usually by blowing the built-in fuse to achieve the purpose of disconnecting the circuit. If the fuse is not blown and the circuit needs to be disconnected, it can only be achieved by disassembling the fuse. The operation is complicated and time-consuming

Embodiment 1

[0030] This embodiment discloses a rotary control component, which realizes the connection or disconnection with the external circuit through the rotation, and can be applied to the MSD manual maintenance switch. On the premise that the fuse is not blown, the MSD manual maintenance switch does not need It can be disconnected from the external circuit by removing the fuse, such as figure 1 and figure 2 As shown, the rotation control component 1 includes a connected screw 11, a cover body 12, a rotating cylinder 13 and a copper conducting block 14, wherein the cover body 12 is arranged on the surface of the screw entry end of the rotating cylinder 13; the copper conducting block 14 directly Or indirectly connected to the external circuit, the indirect connection refers to the connection of the copper conducting block 14 with other conductors connected to the external circuit.

[0031] The head of the screw 11 is provided with a knob 15, and the inner wall of the rotating cylin...

Embodiment 2

[0034] This embodiment discloses a new type of MSD manual maintenance switch. The manual maintenance switch has the advantages of simple structure, convenient operation and beautiful appearance. Working mode, that is: when the overload or short-circuit current passes through the fuse, heat will be generated and blown, thereby disconnecting the circuit; if the fuse is not blown, and the circuit needs to be repaired in response to an emergency, it can only be done by disassembling the fuse. To achieve the purpose of breaking the circuit. The MSD manual maintenance switch of this embodiment is used in combination with the rotary control part of Embodiment 1. When the fuse is not blown, the external source circuit is mechanically disconnected or connected through the rotary control part, thereby protecting the safety of the high-voltage system and maintenance personnel. Flexible and easy.

Abstract

The invention provides a rotation control component, which comprises spirally connected screw and rotating drum, wherein the rotating drum is provided with a conduction block; the conduction block isdirectly or indirectly connected with a circuit; a rotating part is arranged at the head of the screw; when the rotating part rotates, the screw can carry out linear motion along the radial directionof the rotating drum, so that the screw is tightly coupled to the rotating drum to fix the rotating drum, or the screw exits from the rotating drum to be separated, thereby taking down the rotating drum to disconnect the conduction block from the circuit. Furthermore, the invention further discloses a manual service switch. The manual service switch comprises an upper cover, a fuse, a fuse holder,connecting conduction bars and the rotation control component, wherein the upper cover, the fuse, the fuse holder and the connecting conduction bars are connected. The manual service switch is used in combination with the rotation control component, and an external circuit is mechanically disconnected or connected through the rotation control component when the fuse is not blown, so that the security of a high-voltage system and maintenance personnel is protected, and the rotation control component and the manual service switch have the advantages of being simple in structure, flexible and convenient to operate and wide in application range.

Description

technical field [0001] The invention relates to the technical field of high-voltage circuit protection, in particular to an MSD manual maintenance switch, in particular to a novel manual maintenance switch with a rotating control component. Background technique [0002] The MDS manual maintenance switch is a commonly used manual operation device in electric vehicles. Its main function is to quickly disconnect the connection of the high-voltage circuit to effectively protect the The safety of maintenance personnel in a high-pressure environment makes the maintenance work in a relatively safe state, and can effectively respond to emergencies and reduce unnecessary losses. A general MSD manual maintenance switch includes a fuse, a plug end and a jack end, wherein the fuse is connected to the plug end, and the jack end is connected to an external high-voltage circuit. The fuse is connected to the external high-voltage circuit. When the high-voltage system is short-circuited, th...
