Description

technical field

[0001] The invention belongs to the technical field of safety protection devices for high-voltage electrical equipment, and in particular relates to a mechanical locking device for an on-off switch of a high-voltage electrical main control cabinet and an interlock mechanism for a door of a sub-control cabinet. Background technique

[0002] The opening and closing switch of the main control cabinet can be an isolating switch, a circuit breaker switch, or a load switch according to the specific configuration. The downstream electrical cabinet of the main control cabinet is usually called a sub-control cabinet. When there are more than one cabinet, it is customary to use Arabic numerals to sort them as cabinet No. 1 and No. 2, and so on. The doors of No. 1 and No. 2 cabinets are numbered as No. 1 cabinet door and No. 2 cabinet door, and so on. . When the opening and closing switch of the main control cabinet is in the closing state, it is absolutely not allowed...

Embodiment Construction

[0020] In order to enable examiners, especially the public, to further understand the structural features and beneficial effects of the present invention, the specific implementation of the present invention is described in detail as follows in conjunction with the drawings and examples:

[0021] Please refer to Fig. 1, as a certain embodiment that is not specifically limited, the applicant has provided a set of main control cabinet cabinet body 1, and this main control cabinet cabinet body 1 is equipped with three sets of sub-control cabinets 5, three sets of sub-control cabinets 5 The control cabinet 5 is used to respond to the voltage (energy) distributed by the main control cabinet 1. If the main control cabinet 1 is defined as an upstream high-voltage electrical cabinet, then the sub-control cabinet 5 can be defined as a downstream high-voltage electrical cabinet. Install the first mechanical locking device 3 at the opening and closing switch 2 adjacent to the main control...
