Embodiment one
As shown in figure 1, being the anti-jump wiring schematic diagram connecting before circuit modification of switch equipped with protective relaying device, this reality
Applying the described protective relaying device of example is RCS-9611C device, and on-off circuit is 17024 switches, and RCS-9611C device is 17024
The protective relaying device of switch.This connection circuit mainly includes RCS-9611C device outside terminal 1 and Switch main body connection part
2 two parts, Switch main body connection part 2 is mainly the trip-preventing circuit in Switch main body, RCS-9611C device outside terminal 1
It is provided with the multiple binding post of two rows, wherein 303 terminals are connected with installation's power source, the terminal on right side and Switch main body connection part 2
Connect, terminal 419,418 passes through X3:33-X3:34 carry out short circuit, and terminal 417,416 passes through X3:35-X3:36 carry out short circuit, this
When RCS-9611C device and 17024 switching circuitry trip-preventing circuit all use, there is parasitic circuit.Shadow by parasitic loop
Ring, after switch closes a floodgate, action indicator board all lights simultaneously for closing relay HWJ, tripping relay TWJ.
Embodiment two
As shown in Fig. 2 being the anti-jump wiring schematic diagram connecting after circuit modification of switch equipped with protective relaying device.This reality
Apply the wiring schematic diagram after a kind of described improvement of example, still include RCS-9611C device outside terminal 1 and Switch main body wire connecting portion
Divide 2 two parts.The present embodiment is with the difference of above-described embodiment one：To outside 419 Hes of RCS-9611C device before
418 terminals pass through X3:33-X3:Disconnect at the short circuit of 34 realizations, terminal 419 is that tripping relay TWJ position signalling directly connects
Come on normally closed contact one end of auxiliary switch QF in switch.Now, in only tripping operation monitoring circuit TWJ in relay protection circuit
Seal in the normally closed contact of switch disconnector auxiliary switch QF, combined floodgate monitoring circuit HWJ is still connected in trip(ping) circuit.When switch exists
Closing position QF disconnect when, tripping relay TWJ dead electricity return it is therefore prevented that when breaker closing position protection device TWJ/
The problem of HWJ relay action simultaneously.
Embodiment three
As shown in figure 3, being a kind of total connection diagram of switch trip-preventing circuit equipped with protective relaying device.The present embodiment institute
The total elementary diagram of a kind of modified model stated.Carry including local operation circuit 3, the internal trip-preventing circuit 4 of protection device and body
Trip-preventing circuit 5.Local operation circuit 3 provides and controls power supply and handss conjunction, handss to jump the input of the local operations such as input, then with protection
The internal trip-preventing circuit 4 of device is connected, and the internal trip-preventing circuit 4 of protection device carries trip-preventing circuit 5 and on-off circuit again with body
It is connected.Wherein, the internal trip-preventing circuit 4 of protection device carries the concrete mode as above-mentioned reality that trip-preventing circuit 5 is connected again with body
Apply described in example two.
Before not transforming, in the internal anti-jump loop 4 of protection device, when the guard relay TBJ that trips normally divides, closes a floodgate,
On operation impact less.But once there is He Zhong Library circuit, have little time at switch knob 410 to separate or adhesion, or automatically
At the combined floodgate contact YHJ 412 of device during adhesion, without tripping operation guard relay TBJ, switch can occur tripping operation repeatedly,
Close a floodgate, multiple disengagement failure electric current in the short time, this does not allow.The jump phenomena of this switch gently then causes many to system
Secondary Shocks, may make switch explode when serious.After accessing tripping operation guard relay TBJ, when switch manual tripping operation or protection device
During tripping operation, tripping current is had to flow through the tripping operation hold-in winding of TBJ, at this moment the normally closed TBJV2 contact of closing circuit separately, closes a floodgate
Loop is obstructed, if switching signal does not have involution, tripping operation will be made to protect by the normal opened contact TBJV1 of the guard relay TBJ that trips
Hold relay coil TBJV obtain electric so as to self-sustaining, until switching signal returns.Thus play and prevent switch divide-shut brake repeatedly
Effect.
Meanwhile, body carries trip-preventing circuit 5 to complete anti-bouncing function by voltage-type relay, herein for anti-trip relay
K0, when a distant place or switch close a floodgate on the spot, switch is changed into "on" position, switch QF normal opened contact closure from gate-dividing state, starts
Anti-trip relay K0, anti-trip relay K0 self-sustaining junction closure, make anti-trip relay K0 self-sustaining, anti-trip relay K0 is normally closed
Contact disconnects, and closing circuit is obstructed.Switching signal does not disappear, and anti-trip relay K0 does not return, and thus plays and prevents switch anti-
The effect that subdivision is closed a floodgate.
The mode of connection described in the present embodiment, for preventing switch from sending counter to " negative electricity " by anti-jump loop, by relay protection
419 in device, the connection sheet between 418 is opened, and tripping operation supervisory relay TWJ position signalling 419 is directly connected to auxiliary in switch
Help on normally closed contact one end of switch QF, to realize the supervision of switch trip position.By 417 and 416 short circuits, not in outside connected switch
Auxiliary switch QF contact.Only in tripping operation monitoring circuit, seal in the normally closed contact of switch disconnector auxiliary switch QF (see 419 terminals
Draw loop).So when switch disconnects in closing position QF, tripping operation supervisory relay TWJ dead electricity returns it is therefore prevented that in chopper
During closing position, tripping operation supervisory relay TWJ, the problem of combined floodgate supervisory relay HWJ action simultaneously.
The above is only preferred embodiment of the present utility model, not this utility model is made any pro forma
Limit although this utility model is disclosed above with preferred embodiment, but be not limited to this utility model, any familiar
The technical staff of this patent in the range of without departing from technical solutions of the utility model, when can be utilized above-mentioned prompting technology contents make
Go out a little Equivalent embodiments changing or be modified to equivalent variations, as long as being the content without departing from technical solutions of the utility model,
Any simple modification, equivalent variations and modification above example made according to technical spirit of the present utility model, all still belongs to
In the range of this utility model scheme.
