Description
Technical field
The present invention relates to power industry main transformer proving installation, be specially a kind of transformer synthesis test box.
Background technology
The pilot project of transformer is more, test as example taking concrete dielectric loss, testing crew wants wear safety belt to climb transformer, securing band is connected in special hook after climbing up main transformer, carry out high, medium and low voltage three side joint lines, 7 meters of high-power transformer high, medium and low voltage three side maximum distances.Then carry out wiring, testing high voltage dielectric loss over the ground, considers the factor (220kV is that 3 meters, 110kV are that 1.5 meters, 35kV are 1 meter) of personnel and device security distance, and wiring workman must get off from 6 meters of high transformers, guarantee personal safety.In test press over the ground with low pressure over the ground dielectric loss be also same process, in addition also has the sleeve pipe medium loss test of high and medium voltage, only test a project and just need to climb up and climb down 12 times, repeatedly climbing had both extended test period, had increased again personal security hidden danger simultaneously.Therefore need one to increase work efficiency, protect to greatest extent the person and device security, implement the device of State Overhaul Test code comprehensively.
Summary of the invention
The present invention solves in the test of current transformer, to need upper and lower transformer connection ceaselessly not cause work efficiency high and have the technical matters of potential safety hazard, and a kind of transformer synthesis test box is provided.
The present invention adopts following technical scheme to realize: a kind of transformer synthesis test box, comprise a test casing, and the front panel of casing is provided with high, medium and low compression leg, and the back panel of casing is also provided with high, medium and low compression leg; Between high-pressure column on two panels, between middle compression leg and between lower pressure column, be all connected by test casing internal connection line; The front of test casing and the back side are equipped with this binding post top of maskable of a drawing and pulling type and the radome of the left and right sides corresponding to each high, medium and low compression leg.
The present invention, according to the joint categories of test lead, makes the connecting interface corresponding with it, and test lead joint used is converged in a special connecting box.Front panel or back panel are connected with transformer; Then another panel just can be connected with testing tool; Use one by one, accomplish one by one corresponding; Casing is positioned at outside safe distance, change testing tool or be connected with transformer wiring time, do not need to climb up again transformer, only need to change wiring casing is other.Insulation aspect adopts radome to isolate, and in the time measuring, radome is pulled out to a part, by each binding post and contiguous binding post shielding, keeps stable insulation.For the difference of pilot project in transformer test process, need the frequent wiring of changing, by the present invention, transformer is carried out to the accuracy that disposable wiring is increased work efficiency and tested to reduce the number of times of wiring.The arrangement of the connection terminal on high, medium and low compression leg and inner connected mode are those skilled in the art's known technology, and those skilled in the art just can know its implementation after this Shen feelings file of reading.
Use after this device, in the time that main transformer is tested, reduced climbing number of times, shortened test period, reduce again personal security hidden danger simultaneously.Improve work efficiency, protected to greatest extent the person and device security.This device also has the features such as volume is little, wiring is simple.
