The utility model has the advantages of checkout facility work load is little, convenient to use is swift, safe and reliable, be difficult to make mistakes.
Description
Technical field
This utility model is related to all kinds of relay protection device outlet loops and trip test equipment and in particular to a kind of relay
Protection equipment outlet loop and Tripping matrix assay device.
Background technology
In traditional relay protection equipment outlet loop and Tripping matrix are tested, often use using after one protection of outlet
The method that circuit tester measures one by one is carried out, and there is some problem following using circuit tester measurement：1st, workload is big, is often driven one
Protection be both needed to each outlet loop is measured, often set relay protection device often have upper ten kinds of protections, and every kind of protect past
50 times about measurements at least to be carried out toward to there being five about outlets, often carrying out a protective calibration.2nd, security risk is big,
Because partial circuit is energized circuit, circuit tester may be caused in the measurements to burn out or export by mistake.The 3rd, mistake easily occurs, because wanting
The loop of measurement is many, does not slightly note measuring error.4th, two people's measurements are needed, a people throws pressing plate, separately before screen cabinet
An outer people measures after screen cabinet.In sum, the traditional method of relay protection device outlet loop and Tripping matrix use exists
The problems such as during inspection, workload is big, security risk is big and easily mistake.
Utility model content
The technical problems to be solved in the utility model is：For the problems referred to above of prior art, provide a kind of checkout facility
Workload is little, convenient to use, safe and reliable, do not allow error-prone relay protection device outlet loop and Tripping matrix test
Device.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of relay protection device outlet loop and Tripping matrix assay device, including experiment power supply POWER, master control switch
DK and matrix test circuit, the outfan of described experiment power supply POWER switchs DK by master control and is connected with matrix test circuit, institute
State matrix test circuit and include a plurality of test branch road being arranged in parallel, each test branch road includes the display lamp LIGHT connecting
With binding post I1 and I2 for being connected with relay protection device outlet loop.
Preferably, also it is serially connected with protective resistance R in described test branch road.
Relay protection device outlet loop of the present utility model and Tripping matrix assay device tool have the advantage that：This practicality
New inclusion experiment power supply POWER, master control switch DK and matrix test circuit, the outfan of described experiment power supply POWER passes through
Master control switch DK is connected with matrix test circuit, and described matrix test circuit includes a plurality of test branch road being arranged in parallel, each
Bar test branch road include the display lamp LIGHT that connects and for the binding post I1 that is connected with relay protection device outlet loop with
I2, using experiment power supply POWER and display lamp LIGHT, each outlet loop of relay protection device is tried using relay protection
Test line and connect in circuit, when protection act, branch road then accordingly tested by the pressing plate putting into relay protection device outlet loop
Display lamp LIGHT is bright, then accordingly tests the display lamp LIGHT of branch road when disconnecting the pressing plate of relay protection device outlet loop
Go out, carry out relay protection device outlet using relay protection device outlet loop of the present utility model and Tripping matrix assay device
It is only necessary to primary connection can complete the test of all relay protection device outlet loops and Tripping matrix during loop test, reduce
Measurement workload, reduces security risk, decreases the probability made mistakes, and in addition this device carries out outlet loop and tripping operation square
Battle array test when it is only necessary to a people can complete all tests, have checkout facility workload little, convenient to use, safe and reliable,
Do not allow error-prone advantage.
Brief description
Fig. 1 is the circuit theory schematic diagram of this utility model embodiment.
Specific embodiment
As shown in figure 1, the relay protection device outlet loop of the present embodiment and Tripping matrix assay device include test electricity
Source POWER, master control switch DK and matrix test circuit, the outfan of described experiment power supply POWER switchs DK and square by master control
Battle array hookup is connected, and described matrix test circuit includes a plurality of test branch road being arranged in parallel, and each test branch road includes
The display lamp LIGHT of series connection and binding post I1 and I2 for being connected with relay protection device outlet loop.The present embodiment profit
With experiment power supply POWER and display lamp LIGHT, each outlet loop of relay protection device is used reaying protection test line string
In circuit, when protection act, the display lamp of branch road then accordingly tested by the pressing plate putting into relay protection device outlet loop to connection
LIGHT is bright, and when disconnecting the pressing plate of relay protection device outlet loop, then accordingly the display lamp LIGHT of test branch road goes out, and uses
Relay protection device outlet loop of the present utility model and Tripping matrix assay device carry out relay protection device outlet loop examination
It is only necessary to primary connection can complete the test of all relay protection device outlet loops and Tripping matrix when testing, decrease measurement
Workload, reduces security risk, decreases the probability made mistakes, and in addition this device carries out outlet loop and Tripping matrix test
When it is only necessary to a people can complete all tests, have that checkout facility workload is little, convenient to use, safe and reliable, be not easy
The advantage of error.In the present embodiment, in test branch road, also it is serially connected with protective resistance R such that it is able to guarantor is played to display lamp LIGHT
The function of shield, prevents display lamp LIGHT excessively stream or overvoltage from damaging.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonging under this utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, some improvement under the premise of without departing from this utility model principle and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
