Abstract
The present invention is a kind of distribution feeder terminal FTU test devices, belongs to power distribution technical field of automation.It is characterized in that：Pass through the output valve of built-in current feedback circuit simulated high-pressure CT output end currents, give line feed terminals FTU corresponding ports by current output switch switching output, whether each phase measured value, setting valve, alarm parameters and the communication data for testing distribution feeder terminal FTU are correct, and can simulate demarcation switch（Breaker）The test of body point, "on" position, energy storage state and other functions.
Description
Technical field
The invention belongs to power distribution technical field of automation, functional test is carried out to distribution feeder terminal FTU.
Background technology
Distribution feeder terminal FTU, with remote control, remote signalling, fault detection capability, and communicated with power distribution automation main station, it is monitoring and controlling information needed to provide distribution system running situation and various parameters, including parameter when on off state, electrical energy parameter, phase-to phase fault, earth fault and failure, and performs the order that distribution main website is issued, controller switching equipment is adjusted and controlled, fault location, Fault Isolation and non-faulting region fast recovery of power supply function is realized.
The test to distribution feeder terminal FTU has two kinds of modes, first way at this stage：With Switch main body joint debugging mode：With strong current generator, by switching major loop simulated high-pressure line current, performed by distribution feeder terminal FTU and divide, close a floodgate and order in body generation action to test distribution feeder terminal FTU.This mode advantage is：Entirely with composition test environment in kind, distribution feeder terminal FTU and Switch main body can be synchronously detected；Have the disadvantage：Need to match joint debugging with Switch main body, high is required to test environment, test condition, complete equipment volume is big, operation is difficult；The second way：Current signal is produced with multifunctional signal generator, distribution feeder terminal FTU is tested.The advantage of this mode is：Such test equipment can set automatic current curve of output, and output current precision is high；Have the disadvantage：Test equipment price is high, and volume is larger, is not easy to the debugging of distribution feeder terminal FTU producing lines and field maintenance detection, and can not the action of analog feedback Switch main body.
The content of the invention
In order to overcome above-mentioned weak point, the present invention provides a kind of distribution feeder terminal FTU test devices, and it is by test device shell（1）, current feedback circuit（2）, electric current show table（3）, without pressure, without stream switching push button（4）, A phase current output switchs（5）, C phase current output switchs（6）, zero sequence Z/B phase current output switchs（7）, switch knob（8）, opening button（9）, energy storage testing button（10）, functional test button（11）, LS signals input aviation socket（12）, TA electric currents input aviation socket（13）, AC220V power input sockets（14）And internal circuit composition.
The technical solution adopted for the present invention to solve the technical problems is：
First, the output valve of the current feedback circuit simulated high-pressure CT output end currents built in distribution feeder terminal FTU test devices is passed through.
2nd, distribution feeder terminal FTU is given by current output switch switching output, whether A phase currents, C phase currents, zero sequence Z/B current phasor measurements value, setting valve, alarm parameters and the communication for testing distribution feeder terminal FTU are correct.
3rd, when input current value exceedes distribution feeder terminal FTU setting valve, there is over-current phenomenon avoidance, by the way that without pressure, without stream switch switching, simulation main website separating brake is produced without pressure, without stream, and it is whether correct that test distribution feeder terminal FTU performs separating brake output procedure.
4th, this distribution feeder terminal FTU test devices can also pass through LED status display simulation demarcation switch（Breaker）Body point, "on" position.
The beneficial effects of the invention are as follows：Distribution feeder terminal FTU test devices small volume, simple and direct-viewing operation, it is cheap, live corollary equipment can be simulated, global function test is carried out to distribution feeder terminal FTU.By changing cable connector, all different manufacturers in market, the distribution feeder terminal FTU of different size model can be tested.Pass through the use of distribution feeder terminal FTU test devices of the present invention, can effectively it solve in distribution feeder terminal FTU tests, test equipment function is single, price is high, test system is numerous and diverse, and basic unit's installation unit can not fast and effectively be detected to line feed terminals FTU.
