Description

A kind of bus single-subsection and double section wiring anti-incorrect manipulation deadlock control loops
Technical field
This application involves disconnecting switch electric anti-misoperation locked loops to design applied technical field, more particularly to a kind of double Busbar list is segmented and double section wiring anti-incorrect manipulation deadlock control loops.
Background technology
Electric blocking wiring is the important means of power engineering equipment operation locking, for keeping apart for motor-operating mechanism It closes and combines its control loop design electric blocking circuit, electromagnetic lock realization, which can be used, for the disconnecting switch of manual operation electrically closes Lock function.For micro_computer five_proof locking, electric blocking has direct release mechanism control loop, cannot use master key The advantages of spoon unlock, reliability higher.Therefore the conduct of electric blocking circuit is still used in the important circuit such as busbar switch operation Most important anti-misoperation measure.
It is deepened constantly recently as Urbanization in China, electric load wants reliability while rapid growth It asks and also increasingly improves, the application of double-bus section wiring power distribution equipment is increasingly extensive in substation, and conventional double-bus point at present There are incomplete places for the design of the section wiring operation of falling busbar electric blocking circuit.
By taking the conventional bus single-subsection wiring disconnecting switch operation of falling busbar electric blocking circuit as an example, if Fig. 1 is conventional The exclusive circuit schematic diagram of the bus single-subsection wiring disconnecting switch electric blocking of falling busbar wiring, if Fig. 2 is conventional double-bus The main circuit schematic diagram of the single section wiring disconnecting switch electric blocking of falling busbar wiring.
The bus single-subsection wiring main circuit sets three sections of busbares, respectively I busbares, II busbares, III busbares altogether.I is female Line, II busbares are arranged the setting of the outgoing line interval on low voltage control line GBM1 and are latched small busbar, by being set between I busbares, II busbares Mother's I-II busbar breaker auxiliary contact DLM1, I-II mother's mother disconnecting switch 1GM1, the I-II mother's mother disconnecting switch set The disconnecting switch operation of the falling busbar locked loop of 2GM1 composition interlockings;Going out on low voltage control line is arranged in II busbares, III busbares Line interval is arranged GBM2 and is latched small busbar, the mother's II-III busbar breaker auxiliary contact being arranged between being thought by II busbares, mother III DLM2, II-III mother mother disconnecting switch 1GM2, II-III mother mother disconnecting switch 2GM2, the disconnecting switch for forming interlocking are female Line operates locked loop.The section gap both sides disconnecting switch operation of falling busbar electric blocking circuit is independent of one another, no contact.
The conventional double-bus section wiring operation of falling busbar electric blocking circuit is due to section gap both sides bus isolating switch The operation of falling busbar electric blocking circuit is independent of one another, no contact, I busbares, II busbares outgoing line interval only in mother's I-II mother Breaker auxiliary contact DLM1, I-II mother's mother disconnecting switch 1GM1, I-II mother's mother disconnecting switch 2GM1 could when being closed Carry out the operation of falling busbar;II busbares, III busbares outgoing line interval only mother's II-III busbar breaker auxiliary contact DLM2, Mother's II-III mother disconnecting switch 1GM2, II-III mother's mother disconnecting switch 2GM2 can carry out the operation of falling busbar, institute when being closed There is outgoing line interval to cannot achieve the side operation of falling busbar when side mother interval is overhauled, limits the spirit of double-bus section wiring Activity advantage.
Fallen with conventional bus single-subsection wiring female in the conventional two-membrane permeator operation of falling busbar electric blocking circuit Line, which operates electric blocking circuit, has similar connection type.If Fig. 3 is conventional two-membrane permeator disconnecting switch mother The exclusive circuit schematic diagram of line electric blocking wiring, Fig. 4 are that conventional two-membrane permeator disconnecting switch is fallen busbar and electrically closed The main circuit schematic diagram of interlocking line.
Likewise, all outgoing line intervals cannot achieve the side operation of falling busbar when side mother interval is overhauled, limit The flexibility advantage of double-bus section wiring.
Such electric blocking design scheme is often ignored bus section interval and is connect to the busbar operation of falling busbar electric blocking The influence of line, is simply applied mechanically《Power engineering electrical design handbook electric secondary part》Middle double bus scheme isolating-switch locking connects Line scheme, by limit the method for operation or with micro_computer five_proof coordinated scheme, cause the fall busbar operation of double-bus section wiring electrically It is latched the problems such as wiring is incomplete, the method for operation is restricted.
It is then desired to provide one kind can improve the double-bus section wiring operation of falling busbar electric blocking circuit, provide it is a variety of The double-bus section wiring operation of the falling busbar electric blocking loop embodiment of the method for operation.
