Abstract
The utility model discloses an insulating closed device for testing electromagnetic voltage transformators, which comprises a closed testing container, a vacuum pump, an N2 gas storage tank and an SF6 gas storage tank. The vacuum pump, the N2 gas storage tank and the SF6 gas storage tank are respectively connected and communicated with the testing container through a gas transmission branch pipe and a gas transmission main pipe; a gas pressure indicator is installed on the gas transmission main pipe; a fixing bracket is arranged in the testing container; and the testing container adopts a structure of two connected halves which are pressed through a hand vice to be sealed. The device can not only test GIS electromagnetic voltage transformators of 110 kV,, 220 kV and the like before assembly and timely discover defects of the transformators, but also perform universal fit on GIS electromagnetic voltage transformators of different voltage levels, thereby overcoming the disadvantage that for testing electromagnetic voltage transformators made of different factories, models and voltage levels, different closed containers are required to be respectively machined, and having the advantages of convenience, test accuracy, reliable performance and the like.
Description
Technical field
The utility model belongs to electric system detection technique field, particularly a kind of insulation obturator of testing electromagnetic potential transformer.
Background technology
Along with the continuous progress of electric power network technique, GIS is a gas insulated combined electrical equipment in the application of transformer station more and more widely.Yet, when electromagnetic potential transformer carries out on-the-spot commissioning test,, can't finish the test of the excitation property that " Erection works of electrical installations Standard for handover test of electric equipment " require because insulation can't be satisfied high-tension requirement, influence the running quality of electrical network.In the prior art, there is a kind of closed container that utilizes to charge into SF6 gas, to electromagnetic potential transformer capable again technology of installing after carrying out test passes earlier under the state of insulation.Though this technology can solve the test problem of electromagnetic potential transformer excitation property preferably, but, because the faying face of closed container adopts flange to connect, and gather with a plurality of bolts and to compress sealing, though this structure can reach the purpose of accurate detection, but not only dismounting in the process of testing, compress trouble, take a lot of work, testing efficiency is low, and the versatility of device is poor, can not carry out the electromagnetic potential transformer of all size model and electric pressure and test in a covering device, needs the closed container of the different sizes of processing respectively, it is many to cause testing consumable material, the testing cost height.
The utility model content
The utility model provides a kind of can accurately test the electromagnetic potential transformer excitation property, and highly versatile, the insulation obturator of the test electromagnetic potential transformer that testing efficiency is high.
Realize that the technical scheme that the purpose of this utility model is taked is: this device comprises airtight test container, vacuum pump, N2 gas reservoir and SF6 gas reservoir, vacuum pump, N2 gas reservoir and SF6 gas reservoir are connected with test container and UNICOM by gas transmission arm and gas transmission are total respectively, rain glass is housed on the gas transmission main, on each gas transmission arm valve is housed all, be provided with fixed support in the test container, install on the sidewall of test container by the wiring that is used for energized and transmission excitation signal, test container adopts the two halves docking structure that is compressed sealing by hand vice.
The insulation obturator of the test electromagnetic potential transformer of making according to such scheme, by the compress sealing of hand vice to airtight test container, substitute the screw fit sealing, can before assembling, just test realization GIS electromagnetic potential transformers such as 110kV, 220kV voltages, in time find the defective of its existence, can test with the GIS electromagnetic potential transformer device universal fit of different voltage levels and different model simultaneously, and have convenient to operation, test is accurate, advantages such as dependable performance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1: the insulation obturator of test electromagnetic potential transformer of the present utility model is by airtight test container 1, vacuum pump 5, N2 gas reservoir 4 and SF6 gas reservoir 3, wherein, test container 1 adopts the two halves docking structure, the two halves test container is provided with plain flange, and adopts a plurality of hand vices 10 to compress sealing.Be provided with the fixed support 2 that is used for clamping electromagnetic potential transformer 12 in the test container 1, install on the sidewall of test container 1 by the wiring 11 that is used for energized and transmission excitation signal.Vacuum pump 5, N2 gas reservoir 4 and SF6 gas reservoir 3 are connected with test container 1 and UNICOM by gas transmission arm 7 and gas transmission main 8 respectively, rain glass 8 is housed on the gas transmission main 9, be used to monitor the pressure in the test container 1, on each gas transmission arm 7 valve 6 be housed all.This device in use, earlier with test electromagnetic potential transformer clamping to be measured on described fixed support, again two halves test container 1 is docking together, and compresses, guarantee the leakage of test container sealing nothing with hand vice, energized and signal transmission wiring then, can by operating each valve, fill the pressure testing of N2 gas successively, vacuumize, fill SF6 gas by test procedure, guarantee the insulation in the test container 1, carry out excitation characteristic test then.After finishing excitation characteristic test, unclamp hand vice 10, take out electromagnetic potential transformer 12 and get final product, easy to operate quick.This device substitutes the screw fit sealing owing to adopted hand vice to compress sealing, can before assembling, just test realization GIS electromagnetic potential transformers such as 110kV, 220kV voltages, in time find the defective of its existence, can test with the GIS electromagnetic potential transformer device universal fit of different voltage levels and different model, overcome the shortcoming that a producer, a model, an electric pressure all need to process respectively closed container.
