Abstract
The invention relates to a moment measuring device for a circuit breaker body. The moment measuring device comprises a force transducer and a driving mechanism of which one end is used for being connected with an outer crank arm of a circuit breaker, wherein the other end of the driving mechanism is fixedly connected with the input end of the force transducer. The moment during the process of two limit positions of brake separating and closing of the qualified circuit breaker verified by tests is selected as a research object and relevant mechanical principles are combined to measure the moment of a main crank arm of the circuit breaker in the motion process and a standard characteristic curve is drawn for guiding subsequently-operated debugging work of a 800kV circuit breaker body and judging whether the assembly characteristics of the circuit breaker meet the work requirements or not, and thus the debugging time is shortened, the assembly and detection level of the circuit breaker are improved and the characteristics of the circuit breaker are improved.
Description
Technical field
The present invention relates to high-tension switch gear, 800kVGIS isolating switch that especially uses in the high-tension switch gear and potting breaker body dynamometry moment device.
Background technology
Isolating switch operation steady in a long-term is most important, but the debugging of breaker body characteristic for a long time is a complicacy and difficult work debugs later assembly performance can only rely on a series of tests to verify, the cycle is longer.So need a kind of approach of indirect measurement breaker body moment characteristics now; To through the qualified isolating switch of verification experimental verification, measure its moment characteristics, draw out an isolating switch deciliter performance diagram and be used to compare new assembling circuit breaker characteristic; Judge with preliminary whether the isolating switch assembly properties satisfy job requirement; Judge the problem areas that does not meet characteristic, debug targetedly, accelerate the purpose and the accuracy of circuit breaker characteristic debugging.
Summary of the invention
The purpose of this invention is to provide a kind of breaker body dynamometry moment device; In order to measure the moment characteristics of isolating switch; Tentatively judge whether the isolating switch assembly properties satisfy job requirement; Judge the problem areas that does not meet characteristic, debug targetedly, accelerate the purpose and the accuracy of circuit breaker characteristic debugging.
Be to realize above-mentioned purpose, scheme of the present invention is: comprise that a force cell and an end are used for the gear train that is connected with the outer connecting lever of isolating switch, the be connected input end of said force cell of the other end of this gear train.
This breaker body dynamometry moment device, main body adopt steel material to process, and sensor is housed on the device, and an end links to each other with display device, can monitor the moment situation in real time, and is easy to use.Choose moment in the pilot process of the separating brake of the qualified isolating switch of verification experimental verification and two extreme positions that close a floodgate as research object; In conjunction with the associated mechanical principle, measure the moment of isolating switch master connecting lever in motion process and the family curve of drawing standard in real time, in order to the 800kV breaker body debugging work of carrying out after instructing; Judge whether the isolating switch assembly properties satisfy job requirement; Thereby the minimizing debug time improves isolating switch assembling, detection level, improves circuit breaker characteristic.
Further, said force cell connects a display device that is used to show measurement value sensor through a change-over circuit output.
Further, said gear train comprises a screw rod, and screw rod one end is fixedly connected the input end of said force cell, and the screw rod other end is through the nut main connecting lever that removably connects, the outer connecting lever of the hinged said isolating switch of main connecting lever.

Fig. 2 is M curve figure.
Embodiment
Below in conjunction with accompanying drawing the present invention is done further detailed explanation.
LW55-800 type pot type sulfur hexafluoride breaker and ZF27-800 (L) type Cubicle Gas-Insulated Switchgear are outdoor three-phase alternating current 50Hz EHV transmission equipment; Be used for the electric system that rated voltage is 750kV, transmission line of electricity is controlled, measures, protected and switches.
800kV breaker body dynamometry moment device as shown in Figure 1; Comprise a screw rod 1; Screw rod 1 one ends are fixedly connected force cell 4, the nut 2 that is spirally connected on the screw rod 1 (nut 2 positions can be regulated as required), tubular main connecting lever 10 of nut 2 coaxial connections; Main connecting lever 10 is provided with pivot pin 9, and pivot pin 9 is hinged with the outer connecting lever 3 of isolating switch.Force cell 4 connects a display device 14 through a change-over circuit output, and measured value is shown in real time.Said force cell can adopt LOAD CELLS and spring dynamometer etc., and used herein is digital LOAD CELLS.During use, like shown position the dynamometry moment device is installed on the support frame, with pin 11 force cell 4 is fixed on the support frame, lower end, support frame upper end is provided with slide block 12,13.The effect of slide block 12,13 is that the dynamometry moment device is fixed on the breaker body, left and right adjusting position when being convenient to assemble dynamometry square frock framework.
Test is prepared: through the qualified isolating switch of verification experimental verification, make it be in gate-dividing state, shed oil pressure, the closing position of connecting lever outside indicating on the connecting lever box with marking pen, separating brake position, just close position, just branch position etc., the pivot pin that dismounting is connected with main connecting lever.Assemble mechanism case side door not is installed on the support frame position with 800kV breaker body dynamometry moment device main body and two place's slide blocks up and down, and connects with outer connecting lever.Connect sensor and display device, display device is a digital display device, connects the 220V power supply that is used for sensor.
Closing moment is measured: the dynamometry that at the uniform velocity turns round moment device, and make the outer connecting lever that is in the separating brake position slowly turn to closing position, observe digital display device; This moment, moment was comparatively steady; Write down first group of data, when outer connecting lever went to firm chalaza, moment increased suddenly; Then steady once more, observe this process and write down second group of data.Promptly stop test when outer connecting lever goes to closing position, write down the 3rd group of data.
The separating brake torgue measurement: the dynamometry that at the uniform velocity turns round moment device, make the outer connecting lever that is in closing position slowly turn to the separating brake position, observe digital display device; This moment, moment was comparatively steady; Write down the 4th group of data, when outer connecting lever went to firm branch, moment reduced suddenly; Then steady once more, observe this process and write down the 5th group of data.Promptly stop test when outer connecting lever goes to the separating brake position, write down the 6th group of data.
Repeat above-mentioned test for several times, draw family curve according to recorded data.
Use to judge whether new circuit breaker characteristic satisfies job requirement as the standard feature curve.Be illustrated in figure 2 as a family curve.
