Description
Technical field
The utility model relates to a kind of automaton of testing the displacement of relay protection of power system outlet contact, particularly a kind of main transformer, female poor, prepared auto restart outlet logic proving installation.
Background technology
At present, the relay-protection tester of routine is in check multichannel protection contact logic and never breakthrough on actuation time, the actuation time of normally perhaps testing single outlet contact through relay-protection tester through comparatively original multimeter test pulse.Because the general 3-5 in the protective device of various models action back will put in order the group involution second, the protection personnel have to add once more the actuation time that the fault amount is tested other contact, thereby judge action logic.Devices such as outlet contact loop is more, action logic is comparatively complicated main transformer, mother are poor for relating to, prepared auto restart; Existing tester is owing to can not only under the action situation once come out all outlet pulse and time test in a kind of protection; Therefore just need repeatedly do protection test, constantly test the pulse and the actuation time of each outlet pressing plate, add the fault amount again and again; Thereby testing operating time of protection and expending protection personnel great amount of time in logic; Even some protective device also possibly export this no pulse of pressing plate, and the protection personnel thought whole group involution by mistake when test; Thereby can not in time find to protect the mistake around circuitous, wiring error and logic that possibly exist, possibly cause the protective relaying device can not correct operation.For example:
(1) for main transformer protection: the relay protection personnel adjust through test move the contact of outlet.Such as how high back-up protection; General all is through doing mother's couplet, this side and the couplet rebound road that the repeatedly high reserve of experiment test is jumped respectively; But whether other associated loop exists the mistake outlet just to have no idea to test; Whether export and to test protection action repeatedly back and forth, the waste plenty of time if test other contact.3-5 can put in order the group involution second after protective device generally moved during test, did not also know after the involution of the whole group of protection sometimes, and the relay protection test personnel can cause the test of relay protection personnel mistake most probably still according to protecting the action situation to test;
(2) for bus differential protection: the relay protection personnel are often through testing the action outlet logic of protection with the multimeter method of testing; And the multimeter method of testing can not be tested the actuation time of bus differential protection; Therefore can't judge whether the action outlet time meet the demands, each loop-around test will be wasted the plenty of time if desired;
(3) for prepared auto restart: existing relay-protection tester can't be tested the time and the outlet logic of the complete course of action of prepared auto restart; Normally with the prepared auto restart Sectional Test; Its outlet time and logic of test step by step then, the contact that possibly test out like this action is incorrect.
In the first inspection work of newly-built transformer station and transformer station; Require the action logic and the time of one-hundred-percent inspection protection; Yet electric system has at present proposed very high requirement to the duration of protection check; If test according to the conventional method, not only possibly there is certain potential safety hazard, and may causes a lot of engineerings not accomplish on schedule.
Summary of the invention
The purpose of the utility model is to provide a kind of main transformer, female poor, prepared auto restart outlet logic proving installation, and this device can test out the pulse of all outlet ports pressing plate under a kind of protection action situation once.
For achieving the above object; The solution that the utility model adopts is: this outlet logic proving installation comprises to be opened into leaving unit, CPU control module and LCD; Said opening into leaving the unit comprises and opens into module, leaves module and photoisolator; The switching value output contact of wherein leaving module is connected with the switching value input terminal of relay-protection tester; Be used for when button starts relay-protection tester output fault amount; The signal input part of leaving module is connected with the output terminal of photoisolator; Open into module be provided with 16-24 pair with gather interface that contact is connected and the switching value input terminal that is connected with the switching value output contact of relay-protection tester and with trigger the switching value input terminal that the button output contact is connected, the signal output part of opening into module is connected with the input end of photoisolator, opens into leaving the unit to be used to gather contact information and startup of realization switching value or button startup; Said CPU control module comprises gathers contact information translation module, time keeping module, memory module and data processor; The input end of gathering contact information translation module and time keeping module is connected with the output terminal of photoisolator respectively, and the output terminal of gathering contact information translation module and time keeping module is connected with the input end of data processor respectively through memory module; Said LCD is connected with the output terminal of data processor through memory module.
Above-mentioned to open what be provided with into module be 20 pairs with gathering the interface that contact is connected, and wherein 16 pairs are connected with normal opened contact, and 4 pairs are connected with normally closed contact.
The supporting use of the utility model and relay-protection tester adopts switching value to start or button starts, and its course of work is following:
Switching value starts: (closing) contact of opening that at first will gather inserts this device; Again the switching value output contact of relay-protection tester is inserted the switching value input terminal of this device; Open this device power supply then; The protection tester provides start-up time through tester switching value output contact to this device when the test beginning; When collecting certain loop, this device opens and closes the time and the storage of writing down this loop when contact has out (closing) or power source change automatically; When test finishes (can through manually stop or stand-by time is set automatically), microprocessor will be carried test result to LCD, and the relay protection personnel can be protected actuation time of device through LCD;
Button starts: (closing) contact of opening that at first will gather inserts this device; Again this device pass amount output contact is inserted relay-protection tester switching value input terminal; Open this device power supply then; Through relay protection personnel's time, leave the startup input contact of contact input relay protection test fault amount simultaneously through this device by this device of key control startup.Relay-protection tester is after receiving the startup amount of this device, and output fault amount makes the protective device action.When collecting certain loop, this device opens and closes the time and the storage of writing down this loop when contact has out (closing) or power supply displacement automatically; When test finishes (can through manually stop or stand-by time is set automatically); Microprocessor will be carried test result to LCD, and the relay protection personnel can be protected actuation time of device through LCD.
Therefore the utility model can increase work efficiency owing to can under a kind of protection action situation once, test out the pulse of all outlet ports pressing plate greatly, alleviates relay protection personnel's work load, and can effectively avoid leak examination, mistake to try the appearance of situation.
