Description
Technical field
The utility model relates to a kind of protective relaying device servicing unit of actuation time of testing, and utilizes its passive output contact, the actuation time of being convenient to test protective relaying device.
background technology:
At present, substation relay protection device, after installing and using, while doing relay protection check work, the actuation time that often needs to test protective device, is tested exactly protective device and is started rear to sending the exectorial time.
Test operating time of protection, need to have the protection outlet output contact of a pair of protective relaying device, so just direct test action time.But protective relaying device generally do not provide such can coordinate that the test duration uses without source contact.At this moment will add protective number from breaker cabinet terminal row, draw by auxiliary switch for circuit breaker without source contact indirectly testing operating time of protection.The shortcoming of test is that the protective number applying at breaker cabinet need to easily occur error to protective device by secondary cable long-distance transmissions like this, includes the intrinsic actuation time of isolating switch and auxiliary switch the actuation time testing out, and error is larger.
summary of the invention:
For this situation, the utility model provides a kind of test protective relaying device simple in structure, the convenient-to-running servicing unit of actuation time.
The technical solution of the utility model is achieved in that a kind of protective relaying device servicing unit of actuation time of testing, comprise auxiliary reclay, signal lamp and button, described terminal is connected with terminal three once crossing closing by hand button HA, terminal is connected with terminal four once crossing manual opening button FA, terminal three is connected with terminal two through the normally closed contact K31 of auxiliary reclay K1 coil and auxiliary reclay K3, terminal four is connected with terminal two through the normal opened contact K32 of auxiliary reclay K2 coil and auxiliary reclay K3, terminal one is through the normally closed contact K21 of auxiliary reclay K2, the normal opened contact K11 of auxiliary reclay K1 is connected with terminal two with after auxiliary reclay K3 coil, the normal opened contact K33 of auxiliary reclay K3 is also connected in the normal opened contact K11 two ends of auxiliary reclay K1, terminal one is connected with terminal two with open position pilot lamp LD through the normally closed contact K34 of auxiliary reclay K3, terminal one is connected with terminal two with closing position pilot lamp HD through the normal opened contact K35 of auxiliary reclay K3.
The normal opened contact K36 that the terminal Five Classics is crossed auxiliary reclay K3 is connected with terminal six.Terminal seven is connected with terminal eight through the normally closed contact K37 of auxiliary reclay K3.
Beneficial effect: the utility model simplicity of design, be easy to realize, can be as the test protective relaying device servicing unit of actuation time in the time of electrical test.
brief description of the drawings:
Fig. 1 is principle stretch-out view of the present utility model.
specific implementation method:
Below in conjunction with accompanying drawing and enforcement, the utility model is further illustrated.
In Fig. 1, K1, K2 and K3 represent auxiliary reclay; HD represents closing position pilot lamp, and LD represents open position pilot lamp, and HA represents closing by hand button, and FA represents manual brake separating button.What K switch 11 was auxiliary reclay K1 often opens node, and K switch 21 is normally closed contacts of auxiliary reclay K2, and K switch 31, K34 and K37 are the normally closed contacts of auxiliary reclay K3, and K32, K33, K35 and K36 are the normally opened contacts of auxiliary reclay K3.
Terminal one connects direct current+220 volt power supply, and terminal two connects direct current-220 volt power supply, and terminal three is succeeded electrical protective device combined floodgate output contact, and terminal four is succeeded electrical protective device separating brake output contact.Terminal five, six and terminal seven, eight are respectively passive normal opened contact, the normally closed contacts of this servicing unit output, for testing protective device actuation time.
operating principle:
1, original state: after this device terminals one and terminal two are connected with the mains, this device is in gate-dividing state.Now the normally closed contact K34 of auxiliary reclay K3 is in closure state; light LD open position pilot lamp, normally closed contact K31 is in closure state, conducting K1 closing circuit; can accept at any time the closing operation instruction from terminal three, to coordinate the feed motion time of testing protective relaying device.
2, test closing time: when this servicing unit is during in open position, terminal three receives after the combined floodgate order of sending from protective relaying device, auxiliary reclay K1 is by the charged action of normally closed contact K31 of auxiliary reclay, its normal opened contact K11 closure makes the charged action of auxiliary reclay K3, normal opened contact K33 closure realizes K3 self-sustaining, normally closed contact K31 disconnects K1 closing circuit, normal opened contact K32 closure, sub-gate circuit conducting, etc. separating brake to be tested actuation time, normally closed contact K34 disconnects LD open position pilot lamp, normal opened contact K35 closure is lighted HD closing position pilot lamp.Be connected on the normal opened contact K36 of five, six of terminals by assigning to the state of closing, can test protective relaying device from starting to the feed motion time of carrying out the order of closing a floodgate by this contact.
3, test opening time: when this servicing unit is during in closing position, terminal four receives after the separating brake order of sending from protective relaying device, auxiliary reclay K2 passes through now in the charged action of the normal opened contact K32 of closure state, its normally closed contact K21 disconnects auxiliary reclay K3 power-off is returned, its normal opened contact K33 disconnects and removes K3 self-sustaining, the closed conducting K1 of normally closed contact K31 closing circuit, etc. the feed motion to be tested time, normal opened contact K32 disconnects K2 sub-gate circuit, normally closed contact K34 closure is lighted LD open position pilot lamp, normal opened contact K35 disconnects HD closing position pilot lamp.Be connected on the normally closed contact K37 of seven, eight of terminals by assigning to the state of closing, can test protective relaying device from starting to the separating brake actuation time of carrying out separating brake by this contact.
4, leapfrog operation: when this servicing unit is during in open position and need to test opening time, or when this servicing unit is during in closing position and need to test closing time, can correspondingly press hand push button HA or FA, next step test is being carried out in the position that this servicing unit is needed in us, and operating principle is the same.
