Description
Technical Field
The utility model belongs to transformer test tool especially relates to a square wave calibration test operation pole is put in transformer office.
Background
When a 220kV main transformer is subjected to a transformer pulse current partial discharge test, in order to eliminate interference, a worker needs to climb onto a main transformer high-voltage sleeve to be calibrated by using a calibration square wave generator. However, the surface of the porcelain skirt is smooth, so that workers are difficult to climb, and need to lean on the sleeve in a hanging manner by hands when operating the instrument, so that the high-altitude falling risk is very high. Meanwhile, the traditional calibration square wave generator is too large in size, difficult to operate on a transformer, long lead wires are needed for grounding, at least two persons are needed for matching, and operation is inconvenient.
Disclosure of Invention
The to-be-solved technical problem of the utility model is to provide a square wave calibration test operating rod is put in transformer office simple structure, convenient and practical
In order to solve the technical problem, the utility model discloses a following technical scheme:
the transformer partial discharge square wave calibration test operating rod mainly comprises a telescopic operating rod and a square wave generator; the square wave generator is installed at the fixed end of the telescopic operating rod, the square wave generator comprises a test terminal and a grounding terminal, the test terminal is connected with a test wire, and the test wire penetrates through the telescopic operating rod and extends out of the movable end of the telescopic operating rod.
The telescopic operating rod is formed by sleeving three sections of sleeves.
The telescopic length of the telescopic operating rod is 1m-5 m.
Aiming at the problems existing in the calibration of the existing square wave generator, the inventor designs and manufactures a transformer partial discharge square wave calibration test operating rod which mainly comprises a telescopic operating rod and a square wave generator; the square wave generator is installed at the fixed end of the telescopic operating rod, the square wave generator comprises a test terminal and a grounding terminal, the test terminal is connected with a test wire, and the test wire penetrates through the telescopic operating rod and extends out of the movable end of the telescopic operating rod. The utility model discloses collect the test wire in flexible action bars, can extend as required and shorten, solved the frequent sheathed tube safety risk of climbing of testing personnel, also convenient operation simultaneously. The square wave generator is installed at the fixed end of the telescopic operating rod, and an experimenter can set up a high-frequency pulse transmitting loop through the square wave generator, adjust and simulate different discharge amounts of emission, so that the operation of a ground lapping test line and an instrument can be realized, and the working efficiency is improved.
Drawings
Fig. 1 is the structure schematic diagram of the square wave calibration test operating rod is put in transformer office of the utility model.
In the figure: 1 test wire, 2 flexible action bars, 3 square wave generators, 4 test terminals, 5 ground terminal.
Detailed Description
As shown in fig. 1, the square wave calibration and test operating rod for transformer partial discharge of the present invention mainly comprises a telescopic operating rod and a square wave generator 3, wherein the telescopic operating rod 2 can be formed by sleeving a plurality of casing pipes (shown as three sections), and the telescopic length is 1m-5 m; the square wave generator is installed at the stiff end of flexible action bars, and square wave generator contains test terminal 4 and ground terminal 5, and test terminal connects the test wire, and test wire 1 runs through flexible action bars and stretches out from the expansion end of flexible action bars.
When the device is used, the fixed end of the operating rod is held by a hand, the movable end of the telescopic operating rod with the test wire is extended, a high-frequency pulse transmitting loop can be built on the ground, different discharge amounts of simulated emission are adjusted, and therefore the ground can be used for overlapping the test wire and an instrument.
