Description
Technical field
The present invention relates to a kind of power transmission and transforming equipment presence states checking experiment device, thereby relate in particular to, required instrument and equipment and the high-tension apparatus of the on-the-spot shelf depreciation of power equipment is installed on to the test vehicle for partial discharge of power equipment on site that is suitable for mobile operating on a motor vehicle.
Background technology
For newly-built and operating high voltage substation, need to carry out preventative test, overhaul of the equipments or repair based on condition of component to high-tension apparatus, as carry out Partial Discharge Testing on Site.Safe operation in order to ensure high-tension apparatus, when these high-tension apparatuses are tested, the mode in past is that various surveying instruments and equipment are transported to respectively to test site by vehicle, then tested device is carried out to the wiring measurement successively, after a whole set of the test, the staff is organized into report by all test datas again.This traditional method has following drawback: (1) whole process complexity, and employ vehicle and personnel are numerous: because the high-tension apparatus kind is many, kind of test is many, needs wiring repeatedly and change testing tool just can complete the test of all high-tension apparatuses.(2) work efficiency is very low: because the volume and weight of testing tool and equipment is all larger, cause certain difficulty to transportation.During test, also instrument and equipment to be carried from car, tested in rear carrying carriage return, time-consuming.(3) measuring accuracy is impacted: repeatedly carrying easily causes damage to instrument and equipment, can affect data precision; And test site is generally remoter, the weather complexity, make the degree of integration of test data low, and real-time is poor, the error that probably causes the staff to judge.
In order to overcome above-mentioned defect, in prior art, occurred a kind of various test apparatuses being incorporated into to the instruction carriage on car body, as the patent No., be 200620063964.1 disclosed instruction carriages, it is divided into car body to drive occupant area and master control district, in the master control district, be provided with various testing tools, as Insulation Resistance Tester, instrument for measuring DC resistance, the loop circuit tester, the high direct voltage controller, series resonance voltage and transformation shunting switch tester etc., and above-mentioned instrument all is connected with main control computer, in the process of test and test, by outside lead, pilot system is connected with tested equipment, by computing machine, complete experiment work.But this instruction carriage is built-in type, on frame, the outside tie of all test apparatuses all needs to be switched on the concentrated card extender that vehicle body right side band side opens the door, and draws wiring to facilitate to tested device, thereby makes troubles for execute-in-place, and easily make mistakes, work efficiency is lower.
Chinese patent Granted publication CN201382983 has announced a kind of " external mounted electric combined test car " for this reason, this instruction carriage comprises pilothouse, car door is opened in the trunk of afterbody, in the envelope of trunk, be provided with frame along the one side, on frame, be provided with many for power transmission and transforming equipment site test and the required various test apparatuses of State Overhaul Test, on the car body of frame and test apparatus place side, offer uncovered, on uncovered, be equipped with and the uncovered suitable sliding door that can outwards pull open, by opening sliding door, test apparatus directly is connected with tested device, when testing at the scene, only need be pulled outwardly open pull door, test apparatus directly is connected and gets final product with equipment under test.
Above-mentioned two kinds of power test vehicles have only loaded the conventional test instrument, and load, put exciting transformer, put resonance reactor, without office, put the required equipment of local discharge test such as coupling condenser without office without office, need send in addition means of transport will test putting exciting transformer, put resonance reactor, be transported to scene without high pressure testing equipments such as innings putting coupling condenser without office without office of use.After having arrived scene, without office, put exciting transformer, put resonance reactor, put coupling condenser and still will remove and unload, install just and can operate by crane or manpower without office without office, due to without the office put exciting transformer, without the office put resonance reactor, without the office put the coupling condenser volume and quality larger, the simple transportation of loading is easy to extruding or jolts and damage these equipment, and loads and unloads at the scene these equipment and also bring great inconvenience.
The highest trial voltage that also has above-mentioned two kinds of power test vehicles generally below 10kV, can't the finishing equipment rated voltage under local discharge test work.
Summary of the invention
