Description
The present invention relates to a kind of high-voltage circuit-breaker remote control operation locking accident signal and reclosing device in the electric power system.
At an important content that power system transformer substation, hydroelectric station and water conservancy system drainage and irrigation hyelectric power pumping plant is carried out unattended transformation and newly-built conventional design, exactly primary cut-out is set up the remote control function.But start accident signal and reclosing in the time of must guaranteeing the normal occlusion branch of primary cut-out after this function is set up and protect the action separating brake.When (hand divides or the remote control branch), accident signal and reclosing are lockings to primary cut-out at normal separating brake, have only behind combined floodgate (hand closes or remote control is closed) locking just to remove.The remote control separating brake is identical with the course of action of protection separating brake, but both basic differences must locking accident signal and reclosing when being the remote control separating brake, then need start accident signal and reclosing during the protection separating brake.At present, the following two kinds of solutions of domestic most employing realize above-mentioned functions: a kind of is to install accident signal and reclosing block conventional DC auxiliary relay additional at closing circuit, and this auxiliary relay only moves when the remote control separating brake and realizes blocking function by the electric self-sustaining of closing circuit.Its shortcoming one is that DC power supply can not instantaneously be interrupted during blocking function keeps, otherwise this auxiliary relay contact returns, and has removed locking; The 2nd, during the remote control separating brake, the disconnection time limit of the normally closed contact of locking accident signal might lag behind the time limit of returning of the normally closed auxiliary contact of primary cut-out, may the error starting accident signal when causing primary cut-out remote control separating brake.Another kind method is to install accident signal and reclosing block DLS-30A type two-position direct current auxiliary relay separately additional, and this auxiliary relay also only moves when the remote control separating brake and realizes blocking function by mechanical self-sustaining.Its shortcoming one is that specification is many, should select the auxiliary relay of corresponding different size when specifically using by primary cut-out switching current value for use, can not exchange, and costs an arm and a leg; The 2nd, when primary cut-out closes a floodgate (hand closes or remote control is closed), the normally closed contact of locking accident signal return the disconnection time limit that the time limit might be ahead of the normally closed auxiliary contact of primary cut-out, may the error starting accident signal when causing primary cut-out to close a floodgate.
At the defective of above-mentioned two kinds of solutions, the purpose of this invention is to provide that a kind of normal occlusion that guarantees primary cut-out divides and start accident signal during the action of protection separating brake and locking accident signal and reclosing when reclosing, straighforward operation primary cut-out separating brake, reliable in function, installation is simple and direct, cost is low, practical high-voltage circuit-breaker remote control operation locking accident signal and reclosing device.
Design of the present invention is: 1. utilization " bifurcated door bolt " or " magnetic maintenance " principle realizes self-sustaining of the present invention.2. the normally closed contact that adopts instantaneous off delay closure locking accident signal and reclosing reliably when straighforward operation primary cut-out separating brake.No matter 3. the size of breaker closing loop switching current value only need be selected for use with a kind of device to get final product, reduced cost, improved reliability.
Two types on total voltage starting electric current involution type of the present invention and voltage starting voltage involution type.
Accompanying drawing 1 is a principle of the invention block diagram, is numbered binding post of the present invention number among the figure in the circle;
Accompanying drawing 2 is the electrical schematic diagram (embodiment one) of voltage starting electric current involution type of the present invention, and the part among the figure in the frame of broken lines is technology contents of the present invention (except YKH and the YKF);
The present invention is made of shell and printed circuit board plug-in, and shell adopts before the plate have binding post wiring (A11K type) modular housing behind wiring (A11Q type) or the plate, and the self-control plug-in unit is cased, and all electric components are installed on the printed circuit board (PCB) of plug-in unit.
Now in conjunction with the accompanying drawings, technology contents of the present invention is further described.
Core of the present invention is an electric control system.It is made up of working power, startup loop, involution loop, delay circuit, self-sustaining startup and involution executive circuit and contact output circuit six major parts.Working power is direct current 220V, it is introduced by binding post 15,16, after proper transformation, supply with and start loop, involution loop, delay circuit and self-sustaining startup and involution executive circuit conduct working power separately, the startup that starts the loop only needs the voltage pulse signal of a direct current 220V, and the involution in involution loop also only needs the current pulse signal (electric current involution type) of a direct current 0.01-4A or the voltage pulse signal (voltage involution type) of a direct current 220V.
The present invention only has the remote control separating brake to start self-sustaining state and combined floodgate involution self-sustaining state two states.The contact state of contact output circuit is the state after the involution self-sustaining in the accompanying drawing 1, and voltage starting part YBJ in accompanying drawing 2 and the accompanying drawing 3 and electric current involution part YBJ or voltage involution part YBJ are same device.
The remote control separating brake starts the self-sustaining operation principle: after sending the order of remote control separating brake, auxiliary relay normal opened contact YKF closure is carried out in the separating brake remote control, and the voltage starting part YBJ that is connected with binding post 7,8 is charged.At this moment, the instantaneous disconnection of one of the YBJ that is connected with binding post 1,9 time-delay normally closed contact, locking accident signal; The normal opened contact closure of the YBJ that is connected with binding post 4,12 starts the discharge of straighforward operation reclosing, the normally closed contact instantaneous disconnection of while of the YBJ that is connected with binding post 2,10, locking reclosing.After separating brake finished, no matter dc supply has or not, all contacts all utilized " bifurcated door bolt " or " magnetic maintenance " principle to remain at startup self-sustaining state, unless the combined floodgate involution.At this moment, the starting impulse signal does not need to provide for a long time.
Combined floodgate involution self-sustaining operation principle: before sending the order of remote control combined floodgate, the YBJ normally closed contact self-sustaining that is connected with binding post 2,10 is in off-state, the YBJ normal opened contact self-sustaining that is connected with binding post 4,12 is at closure state, and the YBJ timing closing normally closed contact self-sustaining that is connected with binding post 1,9 is in off-state.After sending the order of remote control combined floodgate, auxiliary relay normal opened contact YKH closure is carried out in the combined floodgate remote control, the electric current involution part YBJ (accompanying drawing 2) or the voltage involution part YBJ (accompanying drawing 3) that are connected with binding post 18,20 are charged, cause the instantaneous closure of normally closed contact, the instantaneous disconnection of normal opened contact and the timing closing of timing closing normally closed contact of disconnection, connected the starting recloser loop respectively, disconnected straighforward operation reclosing discharge loop and the accident audio loop has been connected in time-delay.Because time-lag action, guaranteed that reliably the term of execution closing a floodgate accident signal loop remains locking.After combined floodgate finished, no matter dc supply has or not, all contacts all utilized " bifurcated door bolt " or " magnetic maintenance " principle to remain at involution self-sustaining state, unless the remote control separating brake starts.At this moment, the involution pulse signal does not need to provide for a long time yet.
The invention has the advantages that: 1. novel in design unique, blocking function is reliable, effectively guarantees The correct execution of remote-control circuit breaker on/off switch order. 2. cost is low, and installation and maintenance are simple and direct Convenient, good practical effect. 3. applicability is strong, can be widely used in power system transformer substation, water Unattended transformation and the conventional design of power station and water conservancy system drainage and irrigation hyelectric power pumping plant are applied Be worth greatly social and economic benefits and good.
