Embodiment 1

[0030] A control method for a switchgear control system, the switchgear control system includes a control module, and the control module is electrically connected to an LED high-voltage live display system, a voice prompt system, a human body induction system, and a temperature and humidity control system;

[0031] This control method comprises the steps:

[0032] (1) When someone stays in front of the high-voltage switch cabinet, the lighting and alarm lights in the cabinet will be automatically activated and the voice prompts that the cabinet has been powered. Non-professional operators should not approach;

[0033] (2) The LED high-voltage live display system works, and accurately judges whether each phase is charged according to the level;

[0034] (3) The control module controls the opening and closing operations of the circuit breaker, electric handcart and electric grounding knife. When the operator accidentally closes the circuit breaker or operates the isolation switc...

Embodiment 2

[0037] According to the control method of the switchgear control system described in Embodiment 1, the described LED high-voltage live display system works, and the specific steps for accurately judging whether the cabinet door can be opened according to the level are: three-phase high voltage measurement It is sampled by CG series sensors, bridge rectified and filtered to output DC, and then passed through the voltage divider circuit. If the divided voltage value is greater than 0.15 times the bus voltage, the LED indicator light will be on, indicating that the phase is charged.

Embodiment 3

[0039] According to the control method of the switchgear control system described in embodiment 1 or 2, the control module controls the opening and closing operations of the circuit breaker, the electric handcart and the electric grounding knife, and the specific process of controlling the electric handcart is:

[0040] (1) When the electric handcart is in the non-working position and non-test position, the motor of the electric handcart is only allowed to shake out;

[0041] (2) When all the interlocking signals are satisfied and there is no fault, the ready light of the control module will light up, and the control module is allowed to operate;

[0042] (3) When the electric handcart is locked in the process of swinging in, stop the current operation, and drive the electric handcart motor to return to the test position. If the stall occurs again during the return process, stop the operation of the electric handcart motor;

[0043] (4) When the electric handcart is locked in ...

Abstract

Provided is a control method of a switch cabinet control system. At present, the operating state and life of switch cabinets cannot be understood in time and accurately, the operation personnel have to regularly go to the site for manual overhaul, and some hidden troubles cannot be found in time, which is a problem besetting electric power safety production for years. The switch cabinet control system includes a control module which is electrically connected with an LED high-voltage live display system, a voice prompt system, a human body induction system and a temperature and humidity controlsystem. The scheme is used in the control method of the switch cabinet control system.

Description

Technical field: [0001] The invention relates to a control method of a switch cabinet control system, belonging to the technical field of switch cabinet control. Background technique: [0002] Power switchgear is one of the most commonly used equipment in the power field, and its reliability directly affects the safe operation of the power system. However, there are also some safety problems in control: the door of the switchgear is closed during operation, and the operating personnel cannot know the operating status of the main wiring and the working conditions of each equipment in the switchgear on the surface of the switchgear; Insulation problems account for a considerable proportion of operating accidents; the temperature and humidity control in the high-voltage switchgear cannot be ignored; the status and life of the equipment cannot be understood in a timely and accurate manner, etc., and operators have to go to the site for manual maintenance on a regular basis. Hid...
