Description
Technical field
The present invention relates to a kind of isolating switch test macro, relate in particular to a kind of system for testing mechanical properties of integral circuit breaker that can carry out on-line fault diagnosis power high voltage circuit breaker.
Background technology
Primary cut-out is a breaker apparatus important in the electric system, and it is undertaking the dual role that electric system is controlled and protects.In real work; electric system requires primary cut-out to want to carry out branch, combined floodgate fast, swimmingly; to guarantee to play the double action that electric system is controlled and protects; so; the quality of primary cut-out performance, the degree of reliability of work are the key factors of decision power system security power supply, and it is extremely important to keep isolating switch to be in health status all the time.
Show that according to the survey of primary cut-out fault most of faults of isolating switch (70% and minor failure of major failure 86%) occur in mechanism.For many years, in order to keep isolating switch to be in health status all the time, power department mainly relies on traditional plan to examine surely or the mode of preventive trial has a power failure the measurement isolating switch main contact folding lock time, state with indirect understanding breaker mechanism, yet such method of testing exists significantly not enough, promptly can not reflect the state of isolating switch mechanism under high pressure conditions truly.Because in the isolating switch long-time running process, mechanism lubricant can progressively wear out, solidify, certainly will influence the isolating switch regular event.Need isolating switch out of service during this off-line test, isolating switch process out of service is actual to be exactly the breaker open operation process, this process can activate solidified lubricated to a certain extent, branch, the closing time of the isolating switch branch, closing time of testing gained this moment during often with the isolating switch actual motion exists than large deviation, therefore, off-line test can not reflect the state of isolating switch in operational process that obtain exactly.Have hidden danger or fault even if tested out isolating switch in test process, test result can only reflect that also isolating switch is deposited hidden danger or in fault, can not make a definite diagnosis the circuit breaker failure place.
In recent years, electric system is carried out repair based on condition of component energetically and is substituted traditional scheduled overhaul and preventive trial, under the prerequisite that guarantees the healthy operation of power equipment, improve the equipment operation rate, and then raising power supply capacity, power supply quality and power supply reliability, the main prerequisite of repair based on condition of component is carried out on-line testing exactly in equipment running process, according to the more rational turnaround plan of actual health status arrangement of equipment.
The breaker mechanic property of isolating switch test in the past all is to finish with light oscillograph, but because its overall precision is difficult to raising, add that can't carry out data storage is difficult to carry out the follow-up data processing, developed countries just begins to eliminate as far back as the eighties, begins to adopt digital test system and CAT system.Digital test system is to convert the input simulating signal to discrete digital information through A/D converter, and then storage and demonstration, and its typical case is represented as digital storage oscilloscope.Continuous development because of computer technology, make full use of the hyperchannel CAT system that computer development goes out superior performance, join notebook computer, more suitable user's on-the-spot test, interested test figure can be stored on hard disk or the floppy disk and forever preserve, be convenient to follow-up statistical study.Though popular in the market tester cost is very low, easy to use, signal record relies on control signal.
Summary of the invention
The present invention be directed to the deficiency of the said goods, and provide a kind of system for testing mechanical properties of integral circuit breaker, compare with the breaker mechanic property testing tool of isolating switch in the past, the present invention can carry out test-based examination to primary cut-out under the situation of isolating switch high-voltage operation, can reflect truly whether isolating switch is in normal operating conditions under the high voltage situation, and from test result, can also analyze the abort situation of isolating switch, help electric power overhaul personnel quick lock in fault target.
The technical scheme that technical solution problem of the present invention is adopted is:
System for testing mechanical properties of integral circuit breaker comprises main frame, and main frame is provided with interface board, wherein, interface board is provided with p-wire, and interface board is provided with the alternating current-direct current terminal, the velocity test terminal, the vibration-testing terminal, vdct terminal, alternating voltage calibrating terminal, A phase fracture, B phase fracture, C phase fracture and common port terminal, interface board is connected with sensor by p-wire.
Sensor is provided with support and magnetic bases.
The good effect of technical solution of the present invention is:
All passages of the present invention all are analog channels, with 12BIT resolution and 25000Hz speed while true samples, will store behind the analog signal digital, are equipped with special software and make it to become powerful intelligent breaker mechanic property testing system.The most outstanding characteristics are: have abundant programmable function, it triggers setting, comprise triggering mode, channel selecting and triggering level and sampling time-base, recording parameters piece, as all program-controlled setting and unrivaled abundant triggering functions such as record block number, block length and trigger points.This just carries out the high-voltage circuit-breaker status maintenance for electric system desirable effectively testing tool is provided, can be used for on-line testing isolating switch breaker mechanic property, the line data of going forward side by side stores, analyzes contrast, thus the online health status of making a definite diagnosis isolating switch quickly and accurately.
This system for testing mechanical properties of integral circuit breaker has following principal feature:
1. have multiple triggering function: it can utilize input signal to trigger, that is to say, in case have signal to occur on the input channel then harvester triggering automatically, finish the record acquisition function, saved the external trigger signal, and the stationary problem between trigger pip and the measured signal has not been existed, simultaneously, its internal trigger pulse width can program controlly be regulated, and can avoid like this owing to the false triggering phenomenon of disturbing spike pulse to cause;
2. the program-controlled setting of record acquisition speed: the sample rate of CY2000 type data collector is (its highest sample rate and employed port number are irrelevant) from 1000 point/seconds to program-controlled setting 25000 point/seconds;
3. recording capacity is big: the writing time of waveform can be by sample rate and the decision of every passage recording capacity;
4. can the quick repeated in experiments waveform of continuous recording: the repetition rates such as appliance life test, mechanical characteristic test and loaded switch test that these characteristics are specially adapted to the electrical apparatus test station be very high, the requirement that intertrial interval is very short again;
5. special software support: as long as you press " starting record " key, can enter recording status automatically, the waveform that this software will be surveyed at every turn deposits the appointment hard disk areas in automatically by the order of this test, after test is finished, can in order these data files be called in internal memory, show one by one, handle and drawing;
6. support the IEC standard: can be to twice test trip curve comparison;
7. what's new: can support the test of fracture switching-on resistance 50 Ω～500 Ω;
8. test specification is wide: support branch (closing) the lock small current measurement of 50mA, and support the voltage current waveform record to select.
