Description
Technical field
The utility model relates to a kind of pick-up unit, particularly a kind of accumulator load On-line Discharge Detection device.
Background technology
The intelligent station of unmanned or few people's post comprises that transformer station, operating office etc. have many smart machines, these smart machines must adopt direct current supply, normally with carrying out the direct current cabinet of ac-dc conversion as dc power supply, in addition, as safe and reliable guarantee, also must use accumulator as ensureing power supply,, can adopt accumulator that smart machine is ensured power supply in case direct current cabinet breaks down or Alternating Current Power Supply goes wrong.The utilization factor of accumulator is very low, but is very important equipment, must carry out periodic maintenance, detection to it.In the prior art, accumulator and direct current cabinet are electrically connected with smart machine by gauge tap respectively, and direct current cabinet also is electrically connected with accumulator simultaneously, for accumulator provides charge power supply.
Before the accumulator detection, it is as follows to do some preliminary works: the staff need carry numerous checkout equipments, comprise that discharge load, control box, pocket computer and various wire clamp are to the accumulator scene, cut off being electrically connected of accumulator and direct current cabinet and smart machine then, connect accumulator, discharge load, control box and pocket computer in regular turn by various wire clamps.When detecting, open discharge load by the pocket computer sending controling instruction by control box, measure the response parameter of discharge process and discharge back accumulator then, pass through running status and the performance change trend of each index of pocket computer calculating accumulator at last in order to the evaluation accumulator.The weak point of the prior art is: 1, need carry more equipment when detecting, employ more man power and material; 2, need on-the-spot dismounting circuit, very complicated on the step not only, the potential safety hazard that also has misconnection, 3, because the uncertainty of circuit, therefore in the on-the-spot supervision of whole discharge examination process need personnel, add haulage equipment and dismounting circuit, not only complicated loaded down with trivial details, consuming time, the effort of taking a lot of work of above-mentioned prior art, but also have potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of simple, convenient, time saving and energy saving, safe accumulator load On-line Discharge Detection device according to the deficiencies in the prior art part.
The utility model is realized by following approach:
Accumulator load On-line Discharge Detection device, its structural feature is, include change-over switch, discharge load and supervising device, the test side of accumulator is electrically connected with discharge load by change-over switch, the controlled end of discharge load is connected with the control end of supervising device, more than connect and all adopt wired fixedly connectedly, all devices all is installed on accumulator institute at the scene.
All devices all is installed in accumulator institute at the scene, during use, cut off the switch between accumulator and direct current cabinet and accumulator and the smart machine at first respectively, guarantee that accumulator does not influence the normal use of direct current cabinet and smart machine when detecting, the change-over switch of closing then, electric connection accumulator and discharge load are sent out the instruction that triggering begins to discharge by supervising device to discharge load, and discharge load begins accumulator is discharged afterwards.Because all circuits and equipment all are the scenes of being fixedly installed in, therefore need not labor intensive material resources haulage equipment, circuit adopts wired fixed installation to connect in addition, exempted the potential safety hazard that needs the dismounting circuit to be brought in the prior art, guaranteed the stability of circuit simultaneously, testing process must personnel's whole process not supervised, and is both simple and convenient, not only time saving and energy saving saving money also guaranteed safety.
The utility model can further be specially:
Also include an acquisition module, the collection input end of this acquisition module is electrically connected with accumulator, and the output terminal of acquisition module is electrically connected with supervising device.
Acquisition module is to be used for gathering accumulator each supplemental characteristic at whole discharge process, comprise underlying parameter and procedure parameter, feedback transmission is given supervising device then, the supervising device feedback data adjustment that just can provide according to acquisition module or each performance index of calculating accumulator discharge like this, thus the degree of accuracy of calculating improved.
In the prior art, pocket computer sends the standard steering order by control box, and discharge load is according to this instruction works, then according to the performance index of the underlying parameter of setting in the standard steering order in conjunction with each the procedure parameter calculating accumulator that records with various instrument.The weak point of doing like this is, though control box sends the standard steering order according to computing machine, but in fact the standard steering order can't make discharge load accurately be operated on the underlying parameter position of standard, but can be subjected to the aging of various losses such as instrument and meter, equipment and testing environment influence, often the guiding discharge load can't be carried out work with the standard of underlying parameter.If computing machine still will cause the result of calculation deviation bigger with underlying parameter as the calculated value of performance index this moment, even do not have the runnability of correct response accumulator, cause existing potential safety hazard.
Acquisition module is not only gathered the procedure parameter of accumulator, also gathers its underlying parameter simultaneously, and supervising device just can improve the accuracy of calculating when calculating like this, and institute's result calculated more meets the performance condition of the accumulator of surveying.
The utility model can also further be specially:
The inventor carries out following selection to above-mentioned each device:
