Description
Technical field
The utility model belongs to power technology, especially relates to a kind of intelligence can setting, regulate disconnector opening speed and break distance to simulate test unit structure during artificial hot line job non-loaded cable circuit.
Background technology
During hot line job, need manual operation to connect, disconnected drainage nonloaded line, the opening and closing of the similar disconnector of its process.The divide-shut brake of the 10kV disconnector that power distribution network uses in a large number has manual hand manipulation's mode and electric operating two kinds of modes, motor-operating mechanism due to have frequent operation convenient, can the feature such as Long-distance Control divide-shut brake, progressively be applied in power distribution network at present, its electric isolating switch is its point, closing speed and fracture distance are chosen in advance, do not possess the function of adjustment opening speed and fracture distance, disconnect in simulation in the experimental study of nonloaded line electric current and cannot meet the demands.
Summary of the invention
The purpose of this utility model be in order to overcome the existing electric isolating switch in above-mentioned market can not step by step speed governing and to control point, the problem of combined floodgate stroke and provide one can adjustment disconnector opening speed and to control point, combined floodgate stroke, the test unit of fracture distance is opened in adjustment step by step, can according to different research, to realize easily changing disconnector point, closing speed and control divide-shut brake stroke.
The utility model solves the technical scheme that its technical matters adopts:
A kind of hot line job artificial intelligence test unit, the utility model feature is, is is sequentially connected and composed by Programmable Logic Controller, frequency converter, three phase electric machine, reduction gear box, disconnector; Wherein control section comprises Programmable Logic Controller and frequency converter; Powered part adopts the divide-shut brake of disconnector to be rigidly connected by the transmission shaft of three phase electric machine and powered part; Three-phase primary power exports three phase electric machine to by Frequency Converter Control, and three phase electric machine drives disconnector to carry out divide-shut brake by reduction gear box; The adjustment of divide-shut brake speed changes out-put supply frequency control by frequency converter, and the distance of divide-shut brake stroke is by Controlled by Programmable Controller.Achieved the goal by the adjustment of three-phase supply turn-on time and out-put supply frequency.
The beneficial effects of the utility model are:
By Intelligent adjustment disconnector opening speed, fracture distance, the utility model can come that analog manual operation connects well, speed required for disconnected drainage nonloaded line and opening apart from parameter, realizes experimental study object.

Embodiment
See Fig. 1, Fig. 2, a kind of hot line job artificial intelligence test unit, the utility model feature is, is is sequentially connected and composed by Programmable Logic Controller, frequency converter, three phase electric machine, reduction gear box, disconnector; Wherein control section comprises Programmable Logic Controller and frequency converter; Powered part adopts the divide-shut brake of disconnector to be rigidly connected by the transmission shaft of three phase electric machine and powered part; Three-phase primary power exports three phase alternating current motor to by Frequency Converter Control, and three phase electric machine drives disconnector to carry out divide-shut brake by reduction gear box; The adjustment of divide-shut brake speed changes out-put supply frequency control by frequency converter, and the distance of divide-shut brake stroke is by Controlled by Programmable Controller.Achieved the goal by the adjustment of three-phase supply turn-on time and out-put supply frequency.
In Fig. 1, electric machine rotational axis and gear case are combined together, and gearbox drive axle and disconnector rotation axis, by being rigidly connected, rotating simultaneously and drive moving contact and fixed contact of isolating switch to be separated.When three-phase supply enters motor coil, motor is rotated through through-drive and drives disconnector to divide, close a floodgate.
In Fig. 2, Programmable Logic Controller setting rotating output time signal, manual operation main story, reversion start button, output signal to frequency converter, frequency converter sets power supply in advance and to adjust frequency, upon receiving the initiation signal, frequency converter starts, and exports variable-frequency power sources to three phase electric machine, when receiving stop signal, frequency converter stops, and disconnects three-phase out-put supply.Its time control accuracy is at Millisecond.
The distance that opening speed is opened by the three-phase supply output time adjusted and disconnector calculates, open distance to be measured by artificial slide calliper rule, by the power supply output time adjusting different, frequency converter out-put supply frequency is set, can the Study of the Realization test needed for disconnector opening speed and fracture distance.
