Abstract
The utility model provides a five prevent blocking device and computer protection device's wiring circuit, add between five prevent blocking device and computer protection device on the spot, the distant place checkpost, with five prevent blocking device's remote control blocking contact and the parallelly connected back of remote control unblock contact, two distant place operation contacts of rethread are connected with computer protection device's remote control three-phase combined floodgate relay and remote control three-phase tripping relay respectively, through two on the spot operation contacts respectively with computer protection device's manual combined floodgate button and manual separating brake button be connected. Therefore, on-site and remote operation is realized through five-prevention locking, the switch is subjected to five-prevention locking at the working position and the testing position, on-site and remote operation is realized, misoperation is effectively prevented, the access position and the wiring method of the five-prevention locking device are standardized, the operation program is unified, and the working efficiency is improved.
Description
Technical field
The utility model belongs to the electric system protection device field, relates in particular to a kind of wiring circuit that is used between five-defence block device and the microcomputer protecting device.
Background technology
So-called " five is anti-" is meant that the mistake deciliter circuit breaker, on-load deciliter isolating switch, charged extension (closing) earth connection (earthing device), mistakenly entering charged chamber, the band ground wire (ground connection disconnecting link) that in the electrical operation operation, prevent close these five kinds of ingrained bad habit operations of circuit breaker (isolating switch).Yet; In the operation of electrical operations such as power plant, electric substation, still often take place owing to the serious accident that causes is operated in above-mentioned five kinds of ingrained bad habit; And even cause electric equipment to damage the generation of human casualty accident, make the safe operation of electric power system receive serious threat.For this reason, power department has been formulated the strict measure that prevents to above-mentioned five kinds of serious accidents, promptly takes " five-defence block " system.Independent micro_computer five_proof locking device and Microcomputer Protection comprehensive automation device are almost all used in the electric power system of smelter at present, in both combinations, variety of issue occurs through regular meeting, cause the accident of five-defence block inefficacy or protection misoperation to take place.
Summary of the invention
The purpose of the utility model aims to provide a kind of simple, and is safe and reliable, can prevent effectively that five-defence block lost efficacy, and avoided the five-defence block device of misoperation accident and the wiring circuit of microcomputer protecting device.
For this reason, the solution taked of the utility model is:
The wiring circuit of a kind of five-defence block device and microcomputer protecting device comprises five-defence block device and microcomputer protecting device, it is characterized in that, between five-defence block device and microcomputer protecting device, sets up on the spot, distant place clamp (QK); The romote controlled locking contact (A) of five-defence block device with after remote controlled unlocking contact (B) is parallelly connected, is connected with remote operation contact inlet terminal (1), remote operation contact inlet terminal (5), local operation contact inlet terminal (3) and the local operation contact inlet terminal (7) of distant place clamp respectively again; Remote operation contact outlet terminal (2) links to each other with remote control three-phase closing relay (YKHJ) button of microcomputer protecting device; Remote operation contact outlet terminal (6) links to each other with remote control three-phase tripping relay (YKTJ) button of microcomputer protecting device; Local operation contact outlet terminal (4) is connected with the closing by hand button (HA) of microcomputer protecting device, and local operation contact outlet terminal (8) is connected with the manual brake separating button (TA) of microcomputer protecting device.
The good effect of the utility model is:
Since the utility model will " five anti-" locking device insert this open circuit control power positive end and on the spot, between the clamp of a distant place; Realized on the spot with remote operation all through " five is anti-" locking; Switch all passes through " five is anti-" locking and is implemented on the spot and remote operation in service position and test position, thereby:
1, rationally utilizes " five is anti-" locking device, effectively prevent misoperation;
2, standard the on-position and the mode of connection of " five anti-" locking devices;
3, unify operation sequence and method, improved operating efficiency.
Description of drawings
Accompanying drawing is the wiring circuit interconnect pattern of five-defence block device and microcomputer protecting device.
Among the figure: A is the romote controlled locking contact; B is the remote controlled unlocking contact; QK on the spot, distant place clamp; 1,5 is two inlet terminals of remote operation contact; 2,6 is two outlet terminals of remote operation contact; 3,7 is two inlet terminals of local operation contact; 4,8 is two outlet terminals of local operation contact; YKHJ is a remote control three-phase closing relay; YKTJ is a remote control three-phase tripping relay; HA is the closing by hand button; TA is the manual brake separating button; HJ is a closing relay; TJ is the separating brake relay.
Embodiment
Visible by accompanying drawing, the five-defence block device of the utility model and the wiring circuit of microcomputer protecting device comprise original five-defence block device and microcomputer protecting device.The five-defence block device relates generally to romote controlled locking contact A and remote controlled unlocking contact B; Microcomputer protecting device relates generally to remote control three-phase closing relay YKHJ button, remote control three-phase tripping relay YKTJ button, closing by hand button HA and manual brake separating button TA.
The utility model be between five-defence block device and microcomputer protecting device, set up on the spot, distant place clamp QK.The romote controlled locking contact A that is about to the five-defence block device is with after remote controlled unlocking contact B is parallelly connected, is connected with remote operation contact inlet terminal 1, the remote operation contact of the closing relay distant place clamp terminal 5 that enters the mouth respectively again.And remote operation contact outlet terminal 2 links to each other with the remote control three-phase closing relay YKHJ button of microcomputer protecting device, in order to start closing relay HJ; Remote operation contact outlet terminal 6 links to each other with the remote control three-phase tripping relay YKTJ button of microcomputer protecting device, and deactivation separating brake relay TJ realizes the locking of remote control closing circuit and remote control sub-gate circuit.
Simultaneously, the romote controlled locking contact A of five-defence block device with after remote controlled unlocking contact B is parallelly connected, is connected with local operation contact inlet terminal 3 and local operation contact inlet terminal 7 respectively again; And local operation contact outlet terminal 4 is connected with the closing by hand button HA of microcomputer protecting device, in order to start closing relay HJ; 8 of local operation contact outlet terminals are connected with the manual brake separating button TA of microcomputer protecting device, and deactivation separating brake relay TJ realizes the locking of closing by hand and manual brake separating loop on the spot.
Because original protection outlet starts the loop and does not go here and there in this loop in switch test clinching loop; So just can rationally utilize " five is anti-" locking device; The on-position and the mode of connection of standard " five is anti-" locking device; Unify operation sequence, thereby effectively prevent the generation of various misoperation phenomenons.
