Description

A kind of intelligent high-pressure counter that opens circuit
Technical field
The utility model relates to appliance field, is specifically related to a kind of intelligence counter that opens circuit.
Background technology
The counter of existing isolating switch only shows and adds up the combined floodgate number of times of isolating switch; The quality of counter is the normal operation that can at once directly not influence isolating switch; So whether counter can fail to draw attention by accurate counting, even gone bad and to have resembled timely repairing other equipment.Along with the development of digital transformer substation and the requirement of intelligent grid, counter not only will reflect the action frequency and the action situation of isolating switch, but also will utilize the network transmission information that makes progress.And present counter electric loop is the two ends that are connected on the zygonema circle; The counter coil is received the incoming call back and is driven mechanical action demonstration number of times; Because the bite fault often appears in mechanical part; So count very inaccurately, and counter can only calculate the energising number of times of electric closing coil, machinery thread off (comprising closing by hand) just can't count.Prior problem is that counter is not installed in trip(ping) circuit; There is combined floodgate that tripping operation is just arranged from reason; Just can know the tripping operation number of times so only need counting closes a floodgate; But tripping operation exists electric tripping and hand trip(ping), keeps watch on isolating switch operating state and parameter because old-fashioned counter can't reflect, still is that machinery is threaded off so when breaking down tripping operation, can't judge the electrical control action.Existing counting mode has brought very big trouble for actual service work; As: certain circuit primary cut-out is in operation to steal and jumps (not being the fault tripping operation); Be to belong to mechanical electrical apparatus release problem own to cause jumping steathily; Still the mistake of protecting malfunction or secondary circuit ground connection to cause is jumped, so owing to there is not complete tripping operation counter to be difficult to judge failure cause, this can delay maintenance, prolong electric power feeding time; Therefore, originally the counter of isolating switch can't adapt to the intelligent service requirement of digital transformer substation.
Summary of the invention
The purpose of this invention is to provide a kind of intelligence counter that opens circuit, record tripping operation that can be complete and the number of times that closes a floodgate, and can distinguish mechanical action and electrical action.
A kind of intelligent high-pressure isolating switch counter; By closing contact S1, combined floodgate CS S3, counter BN, separating brake contact S2, separating brake CS S4; Said counter BN is between closing contact S1 and separating brake contact S2, and counter BN is between combined floodgate CS S3 and separating brake CS S4.Said dc positive power inserts host scm from closing contact S1, combined floodgate CS S3, separating brake contact S2, separating brake CS S4 respectively.
Said dc positive power inserts terminal block through lead; Terminal block electricity again inserts two converters; Two converters insert host scm with dc positive power; Said host scm is electrically connected with LCD display, DS1225Y storer, TC35I wireless transmission chip, RTL8109 Ethernet interface respectively, and the subsidiary loop normally opened contact that said closing contact S1 is an isolating switch, said combined floodgate CS S3 are the combined floodgate CS of isolating switch; Said separating brake contact S2 is the subsidiary loop normally closed contact of isolating switch, and said separating brake CS S4 is the breaker open operation CS.
Said host scm also is connected with keyboard.
Owing to be provided with said structure; This intelligent counter is applied in the digital transformer substation intelligent breaker, but the branch of accurate counting isolating switch, combined floodgate number of times, but the life-span of dynamic evaluation isolating switch; Effectively keep watch on branch, the combined floodgate situation of isolating switch; And, finally data transmission can be carried out in several ways, for intelligent grid provides decision-making foundation according to the position of the reading failure judgement of counter.
Description of drawings
Fig. 1 is the open circuit principle schematic of counter of a kind of intelligence of the utility model.
Embodiment
As shown in Figure 1; A kind of intelligent high-pressure isolating switch counter; By closing contact S1, combined floodgate CS S3, counter BN, separating brake contact S2, separating brake CS S4; Said counter BN is between closing contact S1 and separating brake contact S2, and counter BN is between combined floodgate CS S3 and separating brake CS S4.Said dc positive power inserts host scm from closing contact S1, combined floodgate CS S3, separating brake contact S2, separating brake CS S4 respectively.Said dc positive power inserts terminal block 1 through lead; Terminal block 1 electricity again inserts two converters 2; Two converters 2 insert host scm 3 with dc positive power; Said host scm 3 is electrically connected with LCD display 31, DS1225Y storer 32, TC35I wireless transmission chip 33, RTL8109 Ethernet interface 34 respectively, and the subsidiary loop normally opened contact that said closing contact S1 is an isolating switch, said combined floodgate CS S3 are the combined floodgate CS of isolating switch; Said separating brake contact S2 is the subsidiary loop normally closed contact of isolating switch, and said separating brake CS S4 is the breaker open operation CS.Said host scm 3 also is connected with keyboard 35.
Counting closes a floodgate: as shown in Figure 1, dc positive power inserts host scm 3 from the subsidiary loop normally opened contact S1 of isolating switch, and dc positive power inserts host scm 3 from breaker closing CS S3 (closing coil Y3).Host scm 3 is monitored the voltage of normally opened contact S1 and combined floodgate CS S3 simultaneously.S1 closing of contact during breaker closing, host scm 3 are sent the signal that breaker body closes a floodgate.When host scm 3 is received the voltage of combined floodgate CS S3, send the signal of the electric combined floodgate of isolating switch.The number of times of host scm 3 corresponding demonstration breaker bodies and electric combined floodgate, time and preservation during normal the combined floodgate.If 3 signals of receiving S1 of host scm explain that isolating switch possibly be that closing by hand or other reasons cause mechanism's dropout combined floodgate, the problem and the control loop that belong to mechanism have no relations.If 3 voltages of receiving S3 of host scm; Explanation is a breaker control circuit incoming call but breaker body closes not brake application; At this time should find out it is normal switching signal, or relay misoperation or secondary cable earth fault cause that normal in this way switching signal further ascertains the reason again.
The separating brake counting: as shown in Figure 1, dc positive power inserts host scm 3 from the subsidiary loop normally closed contact S2 of isolating switch, and dc positive power inserts host scm 3 from the voltage of breaker open operation CS S4.The voltage of 3 while of host scm monitoring contact S2 and separating brake CS S4; S2 closing of contact during breaker open operation; Host scm 3 sends the signal of breaker body separating brake; Receive S4 incoming call when host scm 3, send the signal of the electric separating brake of isolating switch, number of times, the time of host scm 3 corresponding demonstration breaker bodies and electric separating brake and preserve during normal separating brake.If 3 signals of receiving S2 of host scm explain that isolating switch possibly be that manual brake separating or other reasons cause mechanism's dropout jumping steathily, the problem and the control loop that belong to mechanism have no relations.If 3 signals of receiving switching winding of host scm; Explanation is that breaker open operation control loop incoming call but isolating switch can not separating brakes; At this time should find out it is normal sub-gate signal; Still relay misoperation or secondary cable earth fault cause, normal in this way sub-gate signal and can not further ascertaining the reason again by separating brake.
