Abstract
The invention discloses a kind of prepaid meter loop of 10 kV high-pressure outgoing line for converting station, switch time delayed signal auxiliary contact and signal control element is sealed in prepayment meter control loop, until Substation control background computer, by Substation control background computer, Signal transmissions is entered dispatch automated system and marketing system.Its principle is: when prepayment meter arrearage, prepayment meter junction closure, Signal transmissions enters switching winding, make switch deenergization, at this moment manually will overlap once, when switch closes a floodgate, its switch time delayed signal auxiliary contact is not close immediately and could close after being through certain time-delay, which solves the problem of prepayment meter contact normality to the switching winding number of delivering letters, and when switch time delayed signal auxiliary contact is after time closing, also transfer signal to Substation control background computer simultaneously, Substation control background computer will show prepayment meter arrearage, operator on duty also just stopped operation at once.Thus avoid the problem of switch machine concussion.
Description
Technical field
The invention belongs to station technical field, be specifically related to a kind of prepaid meter loop of 10 kV high-pressure outgoing line for converting station.
Background technology
At present, be, at transformer station 10kV circuit leading-out terminal, conventional high-pressure measurement meter is installed to the metering method at 10kV high pressure supplying water family, monthly regularly carry out recording, checking, and charging work, and adopt prepayment meter device, in the prepayment meter add-assembly of transformer station, be typically employed in 10kV high-voltage switch gear control loop and be connected in series the automatic Controlling vertex of prepayment meter disjunction, when in prepayment meter without time-consuming, i.e. automatic circuit-closing contacts, by the positive supply of contact control bus, there is provided signal to switching winding, make the instantaneous disconnection of high-voltage switch gear, stop to customer power supply.But this control technology can not better coordinate the problem be connected in addition with current substation operation system; switch trip phenomenon can be run at any time in transformer station's actual motion; reason is a lot; line facility fault is had also to have the factor of various false protection; according to operation guidance requirement, as tripping operation, regulation can manually reclosing be once; as being successfully considered as false protection, be that equipment failure appears in circuit if do not achieved.Switch trip is made if run into user because of arrearage; our operator on duty is in confused situation conveniently also wants reclosing once; such problem is also just following; the switch trip caused because belonging to subscriber arrearage is found through actual motion; often can run into the problem of switch machine concussion and the jump repeatedly of switch periods when operator on duty's retry, switch cubicle mechanism time serious, can be caused to damage.
Summary of the invention
The object of the invention is to avoid above-mentioned weak point of the prior art, and a kind of effective minimizing maloperation, stable prepaid meter loop of 10 kV high-pressure outgoing line for converting station easy to use, safe are provided.
Realizing the technical scheme that object of the present invention adopts is: a kind of prepaid meter loop of 10 kV high-pressure outgoing line for converting station; comprise the prepayment meter control loop be made up of switch knob, opening button, combined floodgate auxiliary contact, separating brake auxiliary contact, closing coil, switching winding, protective device and prepayment meter contact; described prepayment meter control loop seals in switch time delayed signal auxiliary contact and signal control element, and described signal control element passes through Substation control background computer by Signal transmissions to dispatch automated system and marketing system.
Because the present invention seals in switch time delayed signal auxiliary contact and signal control element in prepayment meter control loop, until Substation control background computer, by Substation control background computer, Signal transmissions is entered dispatch automated system and marketing system.Its principle is: when prepayment meter arrearage, prepayment meter junction closure, Signal transmissions enters switching winding, make switch deenergization, at this moment manually will overlap once, when switch closes a floodgate, its switch time delayed signal auxiliary contact is not close immediately and could close after being through certain time-delay, which solves the problem of prepayment meter contact normality to the switching winding number of delivering letters, and when switch time delayed signal auxiliary contact is after time closing, also transfer signal to Substation control background computer simultaneously, Substation control background computer will show prepayment meter arrearage, operator on duty also just stopped operation at once.Thus avoid the problem of switch machine concussion and the problem of switch cubicle mechanism damage.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
As shown in Figure 1: a kind of prepaid meter loop of 10 kV high-pressure outgoing line for converting station; comprise the prepayment meter control loop be made up of switch knob 1, opening button 2, combined floodgate auxiliary contact 3, separating brake auxiliary contact 4, closing coil 5, switching winding 6, protective device 7 and prepayment meter contact 8; described prepayment meter control loop seals in switch time delayed signal auxiliary contact 9 and signal control element 10, and described signal control element 10 passes through Substation control background computer 11 by Signal transmissions to dispatch automated system 12 and marketing system 13.
Find through investigation and analysis, when artificial control Closing Switch button makes switch close a floodgate, the contact of prepayment meter does not disconnect, but continues to power to switching winding, so just occurs contradiction, causes switch repeatedly deciliter, occurs that machinery shakes.So, the present invention seals in switch time delayed signal auxiliary contact 9 and signal control element 10 in prepayment meter control loop, until Substation control background computer 11, by Substation control background computer 11, Signal transmissions is entered dispatch automated system 12 and marketing system 13.Its principle is: when prepayment meter arrearage, prepayment meter junction closure, Signal transmissions enters switching winding 6, make switch deenergization, at this moment manually will overlap once, when switch closes a floodgate, its switch time delayed signal auxiliary contact 9 is not close immediately and could close after being through certain time-delay, which solves the problem of prepayment meter contact normality to switching winding 6 number of delivering letters, and when switch time delayed signal auxiliary contact 9 is after time closing, also transfer signal to Substation control background computer 11 simultaneously, Substation control background computer 11 will show prepayment meter arrearage, operator on duty also just stopped operation at once.Thus avoid the problem of switch machine concussion and the problem of switch cubicle mechanism damage.
