Embodiment
As shown in Fig. 1-6; the present invention is divided into working power and controls indication and trip protection output indication test circuit 2, isolating switch breaker tripping and closing and indication test circuit 3, switching value input test circuit 4, communication test circuit 5,6 five circuit units of signal test circuit; the connection terminal of each circuit unit passes through respectively connection circuit 1 access integrated protection and monitoring device 7, thereby in all its bearings integrated protection and monitoring device 7 is tested by each circuit unit.
The present invention utilizes test board to realize the automatic test of integrated protection and monitoring device 7, this test board mentality of designing is to allow the test man only need this integrated protection and monitoring device is put into its test board corresponding position, click again the gentle pressure-controlled point pin of working power gauge tap button, just can allow the external connector of this device be connected with test board formation circuit, complex protection device enters duty and state to be measured; This test board panel adopts the miter angle design simultaneously, and the test man need not to move to go on foot and just knows at a glance the test result of this device.Whole test intensity is very light, and the test duration only needs 30 minutes, has shortened half than test duration in the past, and also preventing error wiring and manual operations test to the spoilage that device brings, have improved complex protection device testing efficiency and accuracy rate greatly simultaneously.
To connection circuit 1 as shown in Figure 2, the air pressure of coming by air compressor is as source of the gas, joins reduction valve and is used for adjustable pressure intensity, and join the 3 position-5 way bidirectional electromagnetic valve and come control cylinder, drives a some needle movement.When pressing push button, solenoid valve A coil gets electric, A gas outlet conducting, the B road keeps original state, promotes cylinder from A gas outlet release air pressure, drives the motion of some pin positive dirction, namely connect with complex protection device outside terminal contact, complete the various functions test of its device; When pressing the disconnection knob, solenoid valve B coil gets electric, B gas outlet conducting, and A road maintenance original state promotes cylinder from B gas outlet release air pressure, drives a pin and moves in the other direction, and namely with the disconnection of complex protection device outside terminal contact, whole complex protection device tested and completed.
Working power controls indicating circuit and trip protection output is indicated test circuit 2 as shown in Figure 3, docks one by one with the complex protection device terminal by pneumatic drive point pin, and test board circuit and complex protection device circuit are connected, and enter the test job state.Complex protection device test board working power control circuit works the AC power input of controlling device.When the AC power gauge tap became closure by disconnection, the AC power pilot lamp was bright, and complex protection device has the power supply input, enters normal operating conditions.Power transfer module DC24V out-put supply is used for supplying with signal 1 pilot lamp to signal 6 pilot lamp simultaneously, in case the inner relay that docks with pilot lamp of device by often open become normally closed, corresponding signal lamp obtains power supply and supplies with and will light, send alarm signal, complex protection device Control output test is completed in expression.Install inner out-put supply DC24V and be connected with the hand resetting control circuit, when manual control involution switch was closed, installing inner hand resetting menu will become 1 by 0, thus finishing device hand resetting functional test.
The test circuits 3 such as isolating switch breaker tripping and closing and indication dock with the complex protection device terminal one by one by pneumatic drive point pin as shown in Figure 4, and test board circuit and complex protection device circuit are connected, and enter the test job state.On figure, the DC24V power supply of sign is supplied with by power transfer module, AC power L and the N power supply after by the AC power gauge tap of device extends comes, the tripping operation outlet of device and closing circuit extend to mimic-disconnecting switch TQ contact after monitoring short circuit, extend to mimic-disconnecting switch HQ contact after combined floodgate outlet and trip circuit monitoring short circuit, when complex protection device exports to a closing pulse signal by combined floodgate, mimic-disconnecting switch closes a floodgate, the co-bit pilot lamp is lighted, and completes the test of complex protection device remote control closing function; When complex protection device exported to a tripping operation pulse signal by tripping operation, the mimic-disconnecting switch tripping operation was jumped the position pilot lamp and is lighted, and completes the test of complex protection device remote control trip avoidance function.Closing by hand is at first closed combined floodgate input control switch, and the closing by hand switch is closed, and mimic-disconnecting switch just can close a floodgate, and the co-bit pilot lamp is lighted, i.e. the functional test of complex protection device closing by hand is completed in expression; Hand trip(ping) is at first closed the input control switch that trips, and fixed trip switch is closed, the mimic-disconnecting switch tripping operation, and a jumping pilot lamp is bright, i.e. and complex protection device hand trip(ping) functional test is completed in expression.When device was not in jumping position and co-bit two states, complex protection device sent the control loop disconnection signal, the conducting of device control loop, and the control loop disconnect lamp is lighted, and expression is completed complex protection device control loop disconnection function and is indicated test.At first standby tripping operation wants complex protection device to send this pulse signal, standby trip(ping) circuit conducting, and standby tripping operation pilot lamp is bright, and standby tripping operation deixis test is completed in expression.
Switching value input test circuit 4 drives some pins by air pressure and docks one by one with the complex protection device terminal as shown in Figure 6, and test board circuit and complex protection device circuit are connected, and enter the test job state.Remote signalling power supply DC24V is provided by device internal electric source module, when remote signalling 1 gauge tap becomes close point by battle one by one to remote signalling 14 gauge tap, the remote signalling 1 that corresponding complex protection device shows becomes connection by disconnection one by one to remote signalling 14 menus, show that each remote signalling circuit working state is normal, thus the test of finishing device remote signalling switching value input function.
The present invention is simple to operate, has simplified greatly in the past that every integrated protection and monitoring device all needs manual wiring and manual test process, has improved testing efficiency and accuracy rate; Employing air pressure reference mark pin is connected with the circuit of device, has saved the inconvenience of each plug outside terminal, has saved cost of labor, has increased the effect of automatic test electric device; Test board intuitively shows test results, the more reliable performance of product; This test board is economic and practical, firm, long service life; Whole circuit adopts Modular function design according to the difference of functional areas, and circuit design is short and sweet, takes into full account compactedness and the convenience of each device.
The above is exemplarily described the present invention by reference to the accompanying drawings; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement of having adopted technical solution of the present invention to carry out, or directly apply to other occasion without improvement, all within protection scope of the present invention.
