Example Embodiment

[0029] Example 1:

[0030] A control method of a switch cabinet control system, the switch cabinet control system includes a control module, and the control module is respectively electrically connected with an LED high-voltage live display system, a voice prompt system, a human body induction system and a temperature and humidity control system;

[0031] The control method includes the following steps:

[0032] (1) When someone stops in front of the high-voltage switch cabinet, the lighting and alarm lights in the cabinet are automatically activated, and a voice prompts the cabinet to be powered on. Non-professional operators should not approach it;

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

[0034] (3) The control module controls the opening and closing operations of the circuit breaker, the electric handcart and the electric grounding knife. When the operator mistaken...

Example Embodiment

[0036] Example 2:

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

Example Embodiment

[0038] Example 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 as follows:

[0040] (1) When the electric handcart is in the non-working position and non-test position, the electric handcart motor is only allowed to swing 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 will allow operation;

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

[0043] (4) When the electric handcart...

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...
