Abstract

The utility model relates to a transformer high voltage testing equipment field relates to a but height -adjusting's square wave calibrating device. By the telescopic link of adjustable length, be used for the calibration square wave impulse generator, be used for the ground joint the earth connection, be used for fixed square wave impulse generator's connecting piece and constitute with the couple that the sleeve pipe end is connected, the telescopic link is connect by the pipe box of many diameters differences and forms to realize that length scalable adjusts, but length is adjusted to optional position rotate clockwise locking, anticlockwise rotation unblock to each festival drawing, the connecting piece is fixed square wave impulse generator with the thinnest a lesson with the telescopic link. The utility model discloses a square wave impulse generator is sent to the transformer bushing tip to the adjustable high of the adjustable telescopic link of multisection, passes through the connecting piece with square wave impulse generator and fixes on the connecting rod in the top, through the earth connection reliable ground, is connected to transformer bushing end at the handheld connecting rod in ground through the couple by the people and implements alignment work to the transformer.

Description

A kind of height-adjustable square wave calibrating installation
Technical field
This utility model relates to transformer high-voltage testing equipment field, is specifically related to a kind of height-adjustable square wave calibration cartridge Put.
Background technology
Transformator carries out, in short-term before inducting-voltage proof and long-time induced voltage test, needing user's wave impulse to send out under power down mode The sleeve pipe termination of high-voltage terminal is injected the transition electric charge of standard and is come calibration instrument tolerance discharge capacity and size, due to transformator by raw device The highest (electric pressure 110kV-550kV of distance increasing distance ground, high-voltage terminal end sleeve pipe termination along with electric pressure;Right Answer bushing termination distance to the ground 5m-10m), it is desirable to enough lift work platforms of height are raised to sleeve end grease head highness, By people, above, hand-held square-wave pulse generator realizes square wave calibration operation, and on the one hand plant equipment proposes higher wanting Asking, on the other hand work efficiency is had a greatly reduced quality.
Utility model content
For technical problem present in prior art, the purpose of this utility model is to provide a kind of height-adjustable square wave school Standard apparatus, carries out square wave calibration before inducting-voltage proof and long-time induced voltage test in short-term solving the transformator of different electric pressure Work.
To achieve these goals, the technical scheme that this utility model is used is: a kind of height-adjustable square wave calibrating installation, By the expansion link of adjustable length, the square-wave pulse generator for calibration, the earth lead for grounding connection, it is used for fixing side The connector of pulse generator and the hook composition connected with sleeve pipe termination, expansion link is by the different pipe socket of many diameters Becoming, telescopically adjustable to realize length, each joint is stretched to optional position can rotate clockwise locking, rotates counterclockwise unblock and adjusts Joint length, square-wave pulse generator is fixed by connector with the thinnest joint with expansion link.
Expansion link outermost layer pipe external diameter 30mm, the longest stretchable 11 meters.
The outward appearance length of square-wave pulse generator is 15*10*5cm, and built-in rechargeable battery can produce the transient electrical of standard Lotus measures discharge capacity and size.
Earth lead is the annealed copper strand wire of a diameter of 4mm, length 15m, can realize square-wave generator shell being reliably connected over the ground.
Hook (5) ф 4mm copper rod is fabricated to question mark shape hook, connects for square-wave generator and transformer sleeve pipe end.
Square-wave pulse generator is delivered to bushing shell for transformer end by the adjustment height of more piece adjustable and retractable bar by this utility model, Square-wave pulse generator is fixed in piece connecting rod in the top by connector, by earth lead reliable ground, by people on ground The hand-held connecting rod in face is received transformer sleeve pipe end by hook connecting and transformator is implemented calibration operation.
Height-adjustable square wave calibrating installation of the present utility model, its beneficial effect shows:
1) height-adjustable square wave calibrating installation is used can arbitrarily to regulate square-wave pulse generator, it is achieved different electric pressures Transformator calibration operation.
2) just can be operated on ground by people, eliminate the dependence to large-scale hoistable platform.
3) either factory still runs erecting bed at transformator, all can extensively apply, easy and simple to handle.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model height-adjustable square wave calibrating installation.
Detailed description of the invention
For further describing height-adjustable square wave calibrating installation of the present utility model, below in conjunction with the accompanying drawings it is made furtherly Bright.
One height-adjustable square wave calibrating installation shown in Fig. 1, by the expansion link 1 of adjustable length, for the side of calibration Pulse generator 2, for grounding connection earth lead 3, for fix square-wave pulse generator connector 4 and with set The hook 5 that pipe end connects forms.
Expansion link 1 is socketed to form by the pipe that many diameters are different, and telescopically adjustable to realize length, each joint is stretched to any position Put and can rotate clockwise locking, rotate counterclockwise unblock regulation length.Expansion link 1 outermost layer pipe external diameter 30mm, the longest draws Stretch 11 meters.
The outward appearance length of square-wave pulse generator 2 is 15*10*5cm, and built-in rechargeable battery can produce the transition of standard Electric charge measures discharge capacity and size.
Square-wave pulse generator 2 is fixed by connector 4 with the thinnest joint with expansion link 1.
Earth lead 3 is the annealed copper strand wire of a diameter of 4mm, length 15m, can realize square-wave generator shell reliably connecting over the ground Connect.
Hook 5 ф 4mm copper rod is fabricated to question mark shape hook, connects for square-wave generator and transformer sleeve pipe end.
This utility model uses and manually regulates axial height, in the way of regulating square-wave generator height, and just can be right on ground by people Transformator carries out calibration operation, and low cost, the suitability are strong, and simple in construction is easy to operate, safe and reliable.The scope of application is With electric pressure different manufacturers any transformer's type product.Carry out in short-term inducting-voltage proof and long-time induced voltage test time square wave school Quasi-work.
Above content is only to design example of the present utility model and explanation, affiliated those skilled in the art couple Described specific embodiment makes various amendment or supplements or use similar mode to substitute, without departing from utility model Design or surmount scope defined in the claims, protection domain of the present utility model all should be belonged to.
