Abstract
The utility model discloses a core hoisting tool for an on-load tap-changer of a transformer, which is characterized in that two ends of each intermediate adjusting rod (5) are inserted into inner threaded holes (4) of an upper vertical column (3) and a lower vertical column (7) respectively, each intermediate adjusting rod (5) is fastened with the corresponding upper vertical column (3) and the corresponding lower vertical column (7) to form a perpendicular vertical column with fastening nuts (6) when being adjusted to a proper height, two ends of a beam (1) are fixed onto the two upper vertical columns (3) respectively to form a door-shaped frame through wing-shaped fixing screws (2), a suspension ring (11) is mounted on the beam (1), a chain block (12) is mounted on the suspension ring (11), each lower vertical column (7) is welded on a footing fixing plate (9), and each footing fixing plate (9) is fixed onto the upper end of a permanent magnetic sucker (10) through footing fixing bolts (8). The core hoisting tool can complete core hoisting of the on-load tap-changer of the transformer safely, reliably, simply and conveniently, and core hoisting overhaul time and cost for the on-load tap-changer can be saved.
Description
Technical field
The utility model includes load switch suspended core instrument, is specifically related to 110kV and 35kV substation transformer on load tap changer suspended core instrument.
Background technology
At present; In the 110kV of Huaian electric company operation, the 35kV transformer station; Major part is distributed in grass roots; As the on load tap changer of 110kV, the important auxiliary device of 35kV main transformer, be that transformer carries out the gear conversion operations under load condition, change the device of transformer secondary output voltage.110KV of Huaian electric company and following transformer adopt SYJ (X) ZZ type on load tap changer, the about 100kg of weight, the about 50cm of diameter, highly about 100cm more at present.On load tap changer needs regular suspended core maintenance, and owing to the mechanical connection reason, contact has just separated in the suspended core process a moment, the strength of needs was bigger, simultaneously, because of the service work requirement, need hover for a long time after on load tap changer hangs out.The present suspended core of company all adopts crane to carry out, and owing to the reason crane Chang Wufa of charged distance construction, has caused the difficulty of suspended core and with the danger of manpower suspended core for old transformer station.And mostly newly-built transformer station is indoor substation, and crane more can't be constructed.
Summary of the invention
The purpose of the utility model is: a kind of on-load tap changers of transformers suspended core instrument is provided; This instrument simple light; Be applicable to the suspended core service work of 110kV, 35kV main transformer on load tap changer; The repair method that replaces traditional use crane suspended core is practiced thrift the repair time and the cost of on load tap changer greatly, makes original heavy service work become simple.
The utility model solves the technical scheme that its technical problem adopted: this instrument comprises crossbeam, upper pillar stand, middle tone pole, lower pillar stand, footing fixed head, permanent magnetic chuck, suspension ring and chain block; The position up and down of middle tone pole respectively has regulates outer silk; All there is the endoporus silk lower end of upper pillar stand and the upper end of lower pillar stand; Insert respectively in the endoporus silk of upper pillar stand, lower pillar stand at middle tone pole two, is adjusted to suitable height and with clamp nut upper pillar stand, lower pillar stand and middle tone pole is tightened to vertical pillars again; Through wing hold-down screw the two ends of crossbeam 1 are separately fixed at and form a door type framework on two upper pillar stands, suspension ring are installed on the crossbeam, and chain block is installed on the suspension ring; Lower pillar stand is welded on the footing fixed head, through the footing set bolt footing fixed head is fixed on the permanent magnetic chuck upper end.
During work, permanent magnetic chuck is adsorbed on the transformer body consumingly, and the suction of permanent magnetic chuck reaches 600kg and plays fixation; The chain block lower end is connected with on the on-load shunting switch, utilizes chain block like a cork on load tap changer to be sling; Utilize the middle part adjusting rod to regulate the height and the levelness of vertical pillars, be applicable to the on load tap changer of different size.
The utlity model has following advantage: 1, hoisting ring penetrates crossbeam; Regulate the lifting center, the middle tone pole inserts in upper pillar stand and the lower pillar stand, regulates height and levelness through the endoporus silk of column and the outer silk of adjusting rod; Maximum height can reach 2.3m, and width is 1.5m; 2, the PML-0.6 type permanent magnetic chuck of the utility model utilization with 600kg suction is fixed on the transformer body, and maximum hoisting weight 400kg can satisfy present 110kV, all the main transformer on load tap changer suspended core job requirements of 35kV electric pressure; 3, split type assembling is simple in structure, and is easy to carry, safe and reliable, can in little space, put to good use, practices thrift on load tap changer suspended core repair time and cost greatly.
