Detailed ways

The reclosing remote switching relay (hereinafter referred to as the relay) of the present invention adds the function of remote switching, local/remote switching without changing the performance and installation size of the original M-3A type The selector switch, so as to realize the function of three-phase one-time reclosing and dispatching remote switching reclosing.

The following coordination is shown in Fig. 1 and Fig. 2 to illustrate the specific wiring relationship and working mode of the relay. Fig. 1 is a functional block diagram of the relay of the present invention, and Fig. 2 is an internal wiring diagram of the relay of the present invention.

The 5 pins of the relay are connected to the positive power supply +KM of the external circuit, and the 11 pins are connected to the negative power supply of the external circuit -KM; the current conversion from DC110V to DC24V is performed by the DC/DC converter; the holding current of the relay is between 0.25A~2A , the delay range is between 0.05S~9.95S.

1. Remote input and withdrawal function

The relay is provided with a local/remote selection switch, which controls the normally open contact K-1 and the normally closed contact K-2 connected to the 24V output of the DC/DC converter.

When the local/remote selection switch is in the remote position, the normally closed contact K-2 is closed, and the two-position relay J6 connected to the contacts K-1 and K-2 returns to control its normally closed contact J6-2 , J6-3 closed.

1) When the 13th pin of the relay receives the reclosing input command issued by the dispatcher from a remote place, the intermediate component J1 connected to the normally closed contact J6-2 acts to control the normally open contact J1- connected to the DC/DC converter 1 closed.

At this time, the two-position relay J3 connected to the normally open contact J1-1 pulls in (pulse width 100MS), and its normally open contact J3-1 closes to achieve the purpose of remote input reclosing. The realization of the reclosing function will be described in detail below. describe. After the reclosing switch is put into operation, because the normally open contact J3-4 is also closed, the LED input indicator light on the relay panel lights up; in addition, because the normally open contact J3-2 and the normally closed contact J3-3 act, the remote input signal contact 15 of the recloser -16 feet, 17-18 feet have signal output.

2) When the 14th pin of the relay receives the reclosing exit command issued by the dispatching room from a remote place, the intermediate component J2 connected to the normally closed contact J6-3 acts to control the normally open contact connected to the DC/DC converter J2-1 is closed.

At this time, the two-position relay J3 connected to the normally open contact J2-1 returns (pulse width 100MS), and the normally open contact J3-1 opens to achieve the purpose of remote exit from the reclosing switch. After reclosing exits, because the normally open contact J3-4 is also disconnected, the LED input indicator light on the relay panel goes out; The signals of 15-16 feet and 17-18 feet are returned.

2. Local/remote selection button function

1) As described above, when the local/remote selection switch selects the remote position, the normally closed contact K-2 is closed, the two-position relay J6 returns, and the normally closed contacts J6-2 and J6-3 are closed, and the dispatch can be made from Remote throwing and retreating reclosing. At the same time, the normally closed contact J6-6 is also closed, so that the green LED remote indicator light on the panel is luminous. At this time, the normally open contact J6-4 is disconnected, and the 19-20 pins of the local signal contact are not connected.

2) When the local/remote selection switch is selected to the local position, the normally open contact K-1 is closed, and the two-position relay J6 acts to make the normally open contact J6-1 close, and the normally closed contacts J6-2, J6-3 Open, the intermediate components J1, J2 lose power, and the two-position relay J3 maintains the original remote switching state. At this time, the dispatching room can no longer change the switching status of the reclosing device from a remote place, and can only take local operations to change the switching status of the reclosing device. Because the normally open contact J6-5 is closed, the red LED on-site indicator light on the panel is illuminated, and the input indicator light is also connected to the closed normally open contact J5-5 to emit light through the diode D1. The normally open contact J6-4 is closed, and the local signal contacts 19-20 are connected.

3. Reclosing function

The relay of the present invention adopts the principle of a novel static reclosing relay, which is functionally the same as that of the existing M3-A reclosing relay, has an anti-jump function inside, and digitally sets the delay reclosing time, which is very convenient, intuitive and reliable .

1) Specifically, when the external circuit breaker is manually closed, pins 1 and 4 of the relay get AC power, which makes the intermediate component J5 connected in series between the two pins act, and makes the normally open contact J5 connected to pin 5 -1 is closed, and then the capacitor C connected to the normally open contact J5-1 through the resistor R4 can be connected to the positive and negative power supply ±KM of the outer circuit for charging; The red LED AC power light connected to the intermediate element J5 is turned on, and the green DC power light connected to the closed normally open contact J5-1 is turned on, and the red blocking light connected to the resistor R4 is also turned on. ; After 15 to 25 seconds, the lock light goes out, indicating that the charging has been completed and it enters the state of waiting for reclosing.

2) After the circuit breaker protection trips, when the local/remote selection switch is selected at the local position (that is, the normally open contact J6-1 is closed), or when the local/remote selection switch is selected at the remote position and at the same time the remote When reclosing is put into operation (that is, the normally open contact J3-1 is closed), pins 1 and 3 of the relay will receive AC power through the auxiliary contact of the circuit breaker, and the intermediate component J4 connected in series between the two pins will act (at the same time as described The intermediate element J5 returns), to control the normally open contact J4-1, J4-2 to close, so that the normally open contact J4-1, J4-2 is connected in series with pins 5 and 11 to communicate with the positive and negative power supply ±KM Time element SJ action.

After a certain time delay, the control relay sends a 100MS closing pulse, that is, the capacitor C discharges to the voltage winding of the intermediate element 1ZJ through the closed time element contact SJ-1, and the voltage winding and current winding of the intermediate element 1ZJ act; The normally open contact 1ZJ-1 connected in series with the current winding of the intermediate element 1ZJ is closed, and through the closed J6-1 or J3-1 (and the closed normally closed contact 2ZJ-1, which will be described in detail below), it will communicate with the relay 7 The pin is connected with pin 9, and a closing command is issued to close the circuit breaker.

When the switch-on command is issued, since the diode D2 is connected in series and connected to the intermediate element J4, the LED AC power supply light is also too bright; at the same time, the red locking light on the panel is on and connected to the The red action light on the voltage winding of the time element SJ is on, the action light is off after the circuit breaker is closed, and the blocking light is off after 15 to 25 seconds of charging.

If a temporary fault occurs on the line, after the circuit breaker is closed successfully, the capacitor C will be recharged, so that the relay is in the state of waiting for reclosing again. If the circuit breaker trips again due to a permanent fault after closing, the capacitor C is too late to charge to the voltage required for the action of the intermediate element ZJ, so the intermediate element 1ZJ cannot act, thereby ensuring only one reclosing.

3) An anti-jump intermediate component 2ZJ, the voltage winding and the normally open contact 2ZJ-2 are connected in series between pins 2 and 11 of the relay.

The current winding of the anti-jump intermediate element 2ZJ is arranged between pins 10 and 12 of the relay to be connected in series in the opening circuit of the external circuit breaker and act when the external circuit breaker is open. (not shown in the diagram of the outer circuit connected here)

When the outer circuit breaker is opened, the current winding of the anti-jump intermediate element 2ZJ acts, and the normally open contact 2ZJ-2 closes. When the 2 pin of the relay has a continuous positive power supply, or the 7 pin of the relay is connected to the current winding of the intermediate element 1ZJ, the voltage winding of the anti-jump intermediate element 2ZJ acts and keeps the normally open contact 2ZJ-2 closed, so that the normally closed contact 2ZJ -1 returns, neither pin 2 nor pin 7 of the relay can be connected to pin 9, and the external circuit breaker cannot be closed, preventing the external circuit breaker from continuing to jump between the opening and closing states.

4) When the circuit breaker is manually opened, the external circuit disconnects the AC power on pins 1 and 3, and pins 1 and 4 of the relay, so that the intermediate components J4 and J5 return, and the reclosing function is blocked.

5) A test button is connected and set on the normally open contact J4-2. When the reclosing remote switching relay is in the running state, press the test button, the intermediate component 1ZJ will act once, and the inside of the relay will also act to issue a closing command. However, the circuit breaker will not reclose in the reclosed state, and the blocking light of the LED on the panel is on.

A kind of application example of reclosing relay of the present invention is as follows:

When the circuit breaker is manually closed, AC power is obtained at pins 1 and 4 of the relay, thereby charging the capacitor C in the relay through the above-mentioned series of internal actions. After the charging is completed, it is in the state of waiting for reclosing.

If the local/remote selection button is switched to the remote position, the internal normally open contact J6-1 of the relay returns, and the relay's closing outlet contacts 7 and 9 are controlled by the relay internal normally open contact J3-1. When dispatching the remote place to switch on reclosing, the intermediate component J1 in the relay will receive the positive power pulse sent by the outer circuit, and through the internal action of the relay, J3-1 will be closed; the closing outlet contacts of the relay, pin 7 and pin 9, have Action exit condition, that is, reclosing function input. When dispatching a remote place to exit the reclosing switch, the intermediate component J2 in the relay will receive the positive power pulse sent by the outer circuit, and through the internal action of the relay, J3-1 will return; It meets the action exit conditions, that is, the reclosing function exits.

If the local/remote selection button is switched to the remote position, the normally open contact J6-1 in the relay is closed; then pin 7 and pin 9 of the closing outlet contacts of the relay meet the action outlet conditions, that is, the reclosing function is turned on.

After the circuit breaker protection trips, if the relay reclosing function is put into use and is in the state of reclosing, make the 1 pin and 3 pin of the relay get AC power through the auxiliary contact of the circuit breaker, and after the internal action of the relay, a closing command is issued, that is, the closing exit contact Pin 7 and pin 9 are connected to close the circuit breaker. If the circuit breaker closes on a permanent fault and trips again, because the capacitor C is too late to charge to the voltage required for the action of the intermediate component 1ZJ, the closing outlet contacts 7 and 9 will not be connected again.

When the circuit breaker is manually opened, AC power is lost on pins 1, 3, and 1 and 4 of the relay, the intermediate components J4 and J5 return, and the reclosing function is blocked.

Therefore, the relay of the present invention solves the problem that the reclosing function of the transmission line protection in the original conventional substation cannot be remotely switched on and off. The principle and technology of the static reclosing relay are equipped with remote control switching function and local/remote selection switch, which improves the product level.

A magnetic cylinder is used inside the relay to maintain the small intermediate relay, which is not affected by the failure of the auxiliary power supply. When the auxiliary power supply of the relay loses power, the remote local state and remote switching state of the relay remain unchanged. After the relay is powered on again, the reclosing function will not be mistakenly withdrawn from the input position, nor will it be mistakenly turned on from the exit position.

The invention realizes the functions of three-phase one-time reclosing and dispatching remote switching and reclosing on the power transmission line. It can cooperate with relay protection to automatically reclose the disconnected circuit breaker. If the fault is temporary, the system will resume operation; if the fault is permanent, it will trip again after reclosing and will not reclose again; and Scheduling can require remote control of the reclosing function according to the operation mode, thereby saving workload.

Although the content of the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description should not be considered as limiting the present invention. Various modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the above disclosure. Therefore, the protection scope of the present invention should be defined by the appended claims.
