Abstract
The invention discloses a prepaid meter loop of 10 kV high-pressure outgoing line for converting station, wherein the prepaid meter control loop is serially connected with a switch delay signal auxiliary contact and a signal control element to reach a control background machine of the converting station, wherein the signal is transmitted to a dispatch automation system and a marketing system via the control background machine of the converting station. The principle is that: when the prepaid meter is defaulted, the prepaid meter joint is closed and a signal is transmitted to the opening solenoid, and then the power is cut off by the switch and is manually coincided; when the switch is switched on, the switch delay signal auxiliary contact is delayed for some time and then closed, thus the invention solves the problem of the prepaid meter joint for sending signal to the opening solenoid under normal state. When the switch delay signal auxiliary contact is delayed and closed, the signal is transmitted to the control background machine of the converting station which displays the default of the prepaid meter, and then the operator on duty will timely stop the operation to avoid the mechanical vibration problem of the switch.
Description
Technical field
The invention belongs to transformer station service technique field, be specifically related to a kind of 10kV of transformer station high-voltage terminal prepayment meter loop.
Background technology
At present, the metering method at 10kV high pressure direct-furnish family at the 10kV of transformer station circuit leading-out terminal conventional high-pressure gauge scale meter to be installed, is monthly regularly copied the nuclear work of knocking off; And adopt the prepayment meter device, in the prepayment meter add-assembly of transformer station, be employed in the automatic Control Node of serial connection prepayment meter disjunction in the 10kV high-voltage switch gear control loop usually; No time-consuming in prepayment meter; Be the auto-closing contact, connect the positive supply of controlling bus, signal is provided to switching winding through contact; Make the instantaneous disconnection of high-voltage switch gear, stop to supply power to the user.But this control technology can not better cooperate the problem that is connected in addition with present substation operation system, in transformer station's actual motion, can run into the switch trip phenomenon at any time, and reason is a lot; There is the line facility fault that the factor of various protection malfunctions is also arranged; According to the operation guidance requirement, like tripping operation, regulation can artificial reclosing once; As successfully be regarded as protecting malfunction, be that equipment failure appears in circuit as not achieving.Make switch trip if run into the user because of arrearage; Our operator on duty is in confused situation also to want reclosing once according to routine; Problem is also just following like this; Find because of belonging to the switch trip that subscriber arrearage causes through actual motion, when operator on duty's retry, run into the jump repeatedly of the problem switch periods property of switch machinery concussion, can cause the damage of switch cubicle mechanism when serious through regular meeting.
Summary of the invention
The objective of the invention is to avoid above-mentioned weak point of the prior art, and a kind of effective minimizing maloperation, the stable 10kV of transformer station high-voltage terminal prepayment meter loop easy to use, safe are provided.
Realize that the technical scheme that the object of the invention adopted is: a kind of 10kV of transformer station high-voltage terminal prepayment meter loop; Comprise the prepayment meter control loop of forming by switch knob, opening button, combined floodgate auxiliary contact, separating brake auxiliary contact, closing coil, switching winding, protective device and prepayment meter contact; Said prepayment meter control loop seals in switch time delayed signal auxiliary contact and signal controlling element, and said signal controlling element is transferred to dispatch automated system and marketing system through transformer station's control background computer with signal.
Because the present invention seals in switch time delayed signal auxiliary contact and signal controlling element in the prepayment meter control loop,, signal is transmitted into dispatch automated system and marketing system through transformer station's control background computer until transformer station's control background computer.Its principle is: when the prepayment meter arrearage, prepayment meter junction closure, signal transmit into switching winding; Make the switch deenergization, manual work at this moment will overlap once, when switch closes a floodgate; Its switch time delayed signal auxiliary contact is not closed immediately but closed through ability after the certain time-delay; This has just solved the problem of prepayment meter contact normality to the switching winding feed signals, and after the time closing of switch time delayed signal auxiliary contact process, has also transmitted signal to transformer station's control background computer simultaneously; Transformer station's control background computer will show the prepayment meter arrearage, and the operator on duty has also just stopped operation at once.Thereby the problem of switch machinery concussion and the problem that switch cubicle mechanism damages have been avoided.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further described:
Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
As shown in Figure 1: a kind of 10kV of transformer station high-voltage terminal prepayment meter loop; Comprise the prepayment meter control loop of forming by 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; Said prepayment meter control loop seals in switch time delayed signal auxiliary contact 9 and signal controlling element 10, and said signal controlling element 10 is transferred to dispatch automated system 12 and marketing system 13 through transformer station's control background computer 11 with signal.
Find that through investigation and analysis when artificial control Closing Switch button closed a floodgate switch, the contact of prepayment meter did not break off, but continue contradiction so just to occur, cause switch repeatedly deciliter, the machinery concussion occurs to the switching winding power supply.So; The present invention seals in switch time delayed signal auxiliary contact 9 and signal controlling element 10 in the prepayment meter control loop; Until transformer station's control background computer 11, signal is transmitted into dispatch automated system 12 and marketing system 13 through transformer station's control background computer 11.Its principle is: when the prepayment meter arrearage, prepayment meter junction closure, signal transmit into switching winding 6; Make the switch deenergization, manual work at this moment will overlap once, when switch closes a floodgate; Its switch time delayed signal auxiliary contact 9 is not closed immediately but closed through ability after the certain time-delay; This has just solved the problem of prepayment meter contact normality to switching winding 6 feed signals, and after the 9 process time closings of switch time delayed signal auxiliary contact, has also transmitted signal to transformer station's control background computer 11 simultaneously; Transformer station's control background computer 11 will show the prepayment meter arrearage, and the operator on duty has also just stopped operation at once.Thereby the problem of switch machinery concussion and the problem that switch cubicle mechanism damages have been avoided.
