Description
Technical field
The utility model relates to power engineering test pick-up unit, is the testing apparatus for power engineering outdoor AC high-voltage isolating switch sensing finger pressure specifically.
Background technology
Disconnector is that in electric system, use amount is maximum, the high-tension switch gear that range of application is the widest.Because outdoor disconnector is to be exposed to the electrical equipment of working in atmospheric environment completely, affected by amblent air temperature condition the most direct and the most serious, its service condition is more severe, easily produces the fault of machinery or electric aspect.Especially fingertip contact portion is easily subject to the invasion and attack of rainwater, dust and harmful gas to produce loose contact and cause heating, provide the spring of sensing finger pressure to anneal and to make pressure decreased because of heating, so more cause fingertip heating formation vicious cycle finally to burn out fingertip and lead to a disaster.When maintenance, often only notice that replacing was obviously lost efficacy and the spring of fracture, and cannot judge and replacing the spring of those pressure decreaseds, like this again in service, the distribution meeting of each fingertip electric current is because of pressure difference difference, the larger distribution of current of difference is more inhomogeneous, will come in contact bad and overheated after long-time running.The heating meeting vicious cycle of fingertip, a bad whole contact of will stretching of fingertip contact is bad.There is the sensing finger pressure of many disconnectores adjustable simultaneously, if adjust pressure adjustment pressure inadequate or each fingertip when maintenance, have difference to there will be equally above-mentioned phenomenon.
Current most maintainer judge current-carrying part contact fine or not according to being exactly to measure its loop resistance, think that loop resistance is in acceptability limit, the service work of current-carrying part just can bring to a happy ending.Actually this is not so, the loop resistance value providing in product description is the value of whole galvanic circle, it comprises bulk resistor and the contact resistance of the parts such as connection terminal, contact tube, fingertip contact, scope is large, nargin is larger, can not directly reflect the variation of contact resistance, galvanic circle path can only be described.Test shows: two pairs of fingertip contacts contact its loop resistance value all in acceptability limit with four pairs of fingertips.Same sensing finger pressure large with minor loop resistance value also not variation substantially.
In all kinds of maintenance helical pitches (rules), standard, there is the regulation of measuring fingertip contact, the survey instrument of recommending is spring balance, in real work, measuring sensing finger pressure will be in high-altitude, not only inconvenient, inaccurate also dangerous with spring balance measuring pressure, the sensing finger pressure of the disconnector of certain structures cannot be measured (as scissor) with spring balance at all.So the regulation that requires measurement fingertip contact is also mere scrap of paper.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of intelligent high-pressure isolating switch sensing finger pressure proving installation, this tester adopts MCU to control, by high-precision pressure sensor, sample, computer measurement, analysis, calculating, then store, show, print test findings, also can realize with the online management of PC and analyze data.Use this tester can effectively solve the measurement problem of high-voltage isolating switch sensing finger pressure, facilitate the maintenance of fingertip spring, guarantee effective operation of disconnector.
The utility model is to realize like this above-mentioned purpose, a kind of intelligent high-pressure isolating switch sensing finger pressure tester, comprise survey sensor unit, it is characterized in that it also comprises computer processing unit, described computer processing unit comprises power module, keyboard load module, MCU module, measurement result analysis module, LCD display module, memory module, print module.Described survey sensor unit is the moving contact of electromechanical integration simulation disconnector, adopts high-precision pressure sensor, coordinates corresponding machined piece, and the moving contact motion process of simulation disconnector, forms cantilevered pressure measurement cell.Described computer processing unit can also comprise RS232 on-line module, realizes PC online by described RS232 on-line module.
