Problems solved by technology

[0002] The switching between the multi-states of the switchgear has undergone the transition from manual switching to automatic switching. Although the existing transformation has replaced the object performing the switching (from hand to machine), it has not been able to break away from the operation ticket, and must follow the operation ticket one step at a time. One-step execution, slow switching, low intelligence

example 1

[0049] This example will show how the spirit of the present invention realizes the switching of the switchgear from the running state to the maintenance state.

[0050] According to Table 3, the state code sequence of the switchgear operating state is 110, the state code sequence of the switchgear overhaul state is 001, that is, the current state code sequence is 110, and the target state code sequence is 001, according to the comparison principle of the present invention, only compare The unit status code of the same component, the comparison result is:

[0051] circuit breaker 1 → 0;

[0052] Handcart 1 → 0;

[0053] Ground knife 0→1.

[0054] According to Table 2 and the current status code sequence 110, it is judged that the switching condition is as follows:

[0055] The necessary switching condition for circuit breaker 1→0 is ground switch 0, and the current status code sequence indicates that the current ground switch is 0, which meets the necessary switching conditi...

Abstract

The invention relates to a switch cabinet multi-state switching method, which comprises the following steps of 1, distributing unit state codes; 2, setting a necessary switching condition for switching the unit state codes; 3, combining state code sequences; 4, comparing the state code sequences; 5, judging the switching condition; 6, executing the switching operation; 7, polling the switching operation. According to the method disclosed by the invention, in the process of executing the switching operation, the switching operation can be executed by only meeting the necessary switching condition without being executed step by step according to an operation order, so that multiple switching operations can be executed simultaneously, the switching speed is obviously improved, a good deal of electrified time is saved, power restoration is performed as soon as possible, and the method has an important significance in reducing power failure loss.

Description

technical field [0001] The invention relates to a multi-state switching method for a switch cabinet. Background technique [0002] The switching between the multi-states of the switchgear has undergone the transition from manual switching to automatic switching. Although the existing transformation has replaced the object performing the switching (from hand to machine), it has not been able to break away from the operation ticket, and must follow the operation ticket one step at a time. One-step execution, slow switching, low intelligence. Improving the switching speed of linked switchgear groups, especially large and complex switchgear groups, can save a lot of power-on time and restore power supply as soon as possible, which is of great significance to reduce power loss. [0003] In view of this, the present invention provides a multi-state switching method of a switchgear, which uses intelligent switching instead of an operation ticket to accelerate switching speed. Co...
