Description
Technical field
The utility model relates to a kind of power transmission and transforming equipment presence states checking experiment device, thereby relates in particular to the instrument and equipment that the on-the-spot shelf depreciation of electrical equipment is required and high-tension apparatus is installed on the on-the-spot partial discharge test car of the electrical equipment that is suitable for mobile operating on the self-propelled vehicle.
Background technology
For newly-built and operating high voltage substation, need carry out preventative test, overhaul of the equipments or repair based on condition of component to high-tension apparatus, as carry out on-the-spot partial discharge test.Safe operation in order to ensure high-tension apparatus, when these high-tension apparatuses are tested, the mode in past is that various measuring instruments and equipment are transported to test site respectively by vehicle, then tested device being carried out wiring successively measures, behind a whole set of completion of test, the staff is organized into report with 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 changes the test that testing tool just can be finished all high-tension apparatuses.(2) work efficiency is very low: because the volume and weight of testing tool and equipment is all bigger, cause certain difficulty to transportation.Also instrument and equipment to be carried from car during test, in the carrying carriage return, time-consuming after test is finished.(3) survey precision is impacted: repeatedly carrying causes damage to instrument and equipment easily, can influence data precision; And test site is general remoter, and the weather complexity makes that the degree of integration of test data is low, and real-time is poor, the error that causes the staff to judge probably.
In order to overcome above-mentioned defective, occurred in the prior art a kind of various test apparatuses being incorporated into test car on the car body, as the patent No. is 200620063964.1 disclosed test cars, it is divided into car body drives 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 linked to each other with tested equipment, finish experimental work by computing machine.But this test car is a built in type, the outside tie of all test apparatuses all needs to be switched on the concentrated keysets that vehicle body right side band side opens the door on the frame, draws wiring with convenient to tested device, thereby makes troubles for execute-in-place, and make mistakes easily, work efficiency is lower.
Chinese patent Granted publication CN201382983 has announced a kind of " external mounted electric combined test car " for this reason, this test car comprises operator's compartment, car door is opened in the trunk of afterbody, be provided with frame along the one side in the envelope of trunk, frame is provided with many and is used for power transmission and transforming equipment in-place test and the required various test apparatuses of repair based on condition of component test, on the car body of frame and test apparatus place side, offer uncovered, be equipped with on uncovered and the uncovered suitable sliding door that can outwards draw back, by opening sliding door test apparatus is directly linked to each other with tested device, when testing at the scene, only need be pulled outwardly open pull door, test apparatus and equipment under test direct connection are got final product.
Above-mentioned two kinds of power test cars have only loaded the normal test instrument, do not put that excitation transformer, no office are put resonance reactor, the required equipment of local discharge test such as coupling capacitor are put in no office and load no office, the no office that need send transportation means will test usefulness in addition puts that excitation transformer, no office are put resonance reactor, no office puts high pressure test facilitys such as coupling capacitor and is transported to the scene.After having arrived the scene, no office puts excitation transformer, no office and puts resonance reactor, no office and put coupling capacitor and still will remove by crane or manpower and unload, install just and can operate, because no office puts excitation transformer, no office and puts that resonance reactor, no office are put the coupling capacitor volume and quality is bigger, the simple transportation of loading is easy to extruding or jolts and damage these equipment, and loads and unloads these equipment at the scene and also bring great inconvenience.
