Description
Technical field
The invention belongs to calibration equipment technical fields, specifically, the present invention relates to a kind of multi-functional non-three phase relays
Tester.
Background technique
According to 18 countermeasures of State Grid Corporation of China: three phase position non-uniform protection of breaker should use breaker sheet
Three phase position non-uniform protection of body.220kV and the above breaker are operated using split-phase, manual operation or automatic reclosing process
In, there are three phase positions caused by three characteristics of the middle term non-Switching Synchronization, the single-pole reclosing reasons such as unsuccessfully are inconsistent, by non-three phase after
Electric appliance forces the tripping of breaker three-phase.Non-three phase relay longtime running is under outdoor rugged environment, by quality, vibration
Etc. factors influence operation a period of time after, error may occur with former setting valve；Unbalanced three-phase lines time setting value becomes smaller, and leads
It causes three phases un identical protection movement to shift to an earlier date than upper level protection act, causes equipment mistrip；Unbalanced three-phase lines time setting value
Larger, unbalanced three-phase lines movement delay, system backup protection act, breaker overstepping causes fault coverage to expand；Open circuit
As long as device three phases un identical protection has breaker, three phase positions is inconsistent, starting relay outlet tripping, without any locking item
Part, so relay performance state is the key factor that breaker body three phases un identical protection correctly acts；To reduce open circuit
Device unbalanced three-phase lines adjusting numerical value is endangered caused by system, should in conjunction with power failure machine meeting, to the unbalanced three-phase lines relay time into
Row verification.Before this we there is no instrument independently relay is verified.
Currently, the non-three phase time relay verification the main problems are as follows:
1, in-site modeling open phase operation of CB process, protection backoff period filter calculate non-three phase relay indirectly
Actuation time, including the sum of non-three phase relay actuation time and switch motion time, disadvantage measurement result not can accurately reflect
Pull up time.
2, non-whole phase protection action test process is related to switching and protecting two professional coordinations, the live work of two professions
The difference for making step causes a side to need to fall into a long wait another party, delays the activity duration, averagely verifies a relay and needs
20 minutes.
3, relay spare part can not be verified individually, and the non-three phase relay spare part of long term storage lacks the instrument directly verified
Device, it is desirable that verified after being installed on breaker, influencing defect elimination quality.

By the way that breaker non-whole phase protection motion analysis, three phase position of breaker is inconsistent, and non-three phase relay starts
Excitation, by n seconds pre-set, string is closed in the non-three phase relay tip of sub-gate circuit, circuit breaker trip: such as Fig. 1 institute
Show, power on device, press power switch 1, be powered to correction instrument of the invention, opening coil switch 21, coil 2 opens
Dynamic, the node conducting of coil 2 starts 41 high potential of timer, timing starts；It crosses time n second (predetermined time), open time delay is opened
31 are closed, delayer (i.e. delay node) movement stops 42 low potential of timer, timing stops；Coil 2 is shown on display 4
Actuation coil switch 21 is closed into the time of the closure of delayer action delay switch 31, the i.e. delay time of non-three phase relay.
As depicted in figs. 1 and 2, specific test process is first to be well placed tester and power supply device, will be outside tester
Shell ground connection, then the measurement end p-wire of tester is connected, non-three phase relay tip is connected with tester with p-wire,
Last joint test power supply line；Then start to test, as shown in Fig. 3~Fig. 6, successively open power supply device cell switch S1,
(the 12V DC electricity of power supply device output exports 220V exchange after intermediate inverter module inversion to inverse switch S2 outward
Electricity), power switch 1, display time of display 4 is 0, voltage 0, adjusts the output voltage of power supply device to rated value, aobvious
Show that the voltage of device 4 is shown as rated value, for example, 220V, actuating coil switch 21, non-three phase relay starts excitation, display
The beginning timer 41 of 4 (i.e. the time relays) starts timing, and by n seconds (presetting the time), delayer 3 was acted, timing
Stop, the time shown at this time is exactly non-three phase relay actuation time.
As shown in Figure 3, Figure 4, the 12V DC electricity of power supply device output is defeated outward after intermediate inverter module inversion
220V alternating current out, 220V alternating current export DC voltage, voltage through rectification after T1 pressure regulation after J1 is input to control circuit
Value is shown in digital display screen；S5 is direct current output switch, and S4 is that direct current drive output switchs, after any closure of the two, coil
Switch 21 conjugates, and control circuit exports DC voltage to busy relay, and D2 is lighted.Start count signal to input from P6, P7, meter
When screen start timing, when test non-three phase relay delay node closure after to P4, P5 node input stop count signal, this
When timing stop.
Tester provided by the invention does not need realistic simulation non-three phase action process, excludes the switch motion time to non-complete
The influence of phase relay time.When main into switch relay setting valve 0.5s, it is with the non-three phase relay tester testing time
When 0.45, data just belong to true scope.
Analysis it is found that compared with prior art, the advantages and beneficial effects of the present invention are:
One, the non-whole phase protection provided by the invention that can accurately measure switch using this non-three phase relay checking instrument is dynamic
Make the time, hidden danger existing for timely discovering device improves equipment reliability of operation；Meanwhile by non-three phase relay
The test of spare part can verify spare part integrity in advance, avoid spare part needs from being installed on switch and simulate and test.In addition with
It needs three people to complete when preceding verification non-three phase relay, switchs professional two people and do experiment, professional people cooperation is protected to see rear number of units
According to.It needs to switch professional two people when present field-checking, one people can be completed when standby redundancy verifies；Again, school of the invention
Checking time can be shortened by testing instrument, verify the non-three phase relay time in the past, and Liang Ge teams and groups is needed to cooperate, about complete at 20 minutes
At；Present split run can both be completed for group job 5 minutes.Tester of the invention has structure simple in a word, easy to operate, measurement
Precision is high, and numerical value shows the features such as accurate, by the popularization and application in work area, reached reduction personnel labor intensity, shortens
Repair time, the effect improved service quality.
Two, the power supply device that the present invention is arranged can enable the invention to use in the place of not power supply.
Three, the unit of testing and controlling that the present invention is arranged, more intuitive can show non-three phase pull up time
It shows and.
Four, the control cabinet and power supply box that are arranged of the present invention, can be convenient carrying of the invention, and by coil 2, delayer
3 and display 4 be placed in control cabinet, power supply device is placed in power supply box, can prevent from having an impact between each other.
As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature
Case is realized.Therefore, embodiment disclosed above, in all respects are merely illustrative, not the only.Institute
