Abstract
The utility model relates to a self-change impedance compensating starter, which is characterized in that the utility model is composed of a tubular iron core and a coil, wherein, the iron core is made of a metal tube with magnetic permeability, and the coil winds outside the iron core. The utility model has the advantages of simple structure, light weight, free zero load, low energy consumption, convenient maintenance and reliable operation without switch-on sparking appearance.
Description
The utility model relates to starting device of motor, and is specifically a kind of from the impedance compensator starter.
The motor of some larger capacities adopts motor starter to carry out reduced voltage starting usually at present, to reduce starting current.The starter that reduced voltage starting adopted mostly is autotransformer greatly, and the iron core of autotransformer is to build up with 0.5～1.2mm silicon steel sheet, its Heavy Weight, and the process conditions complexity, connector lug is many, breaks down easily, and energy consumption is big.
The purpose of this utility model is in order to solve the deficiency that the above-mentioned background technology exists, and proposes a kind ofly have in light weightly, easy to maintenance, and energy consumption is low, and is reliable from the impedance compensator starter.
At the foregoing invention purpose, the utility model adopts following technical scheme, a kind ofly it is characterized in that from the impedance compensator starter it is made of tubular iron core and coil, the metal tube that iron core adopts with magnetic conductivity, and coil is coiling outside iron core.
Before the utility model is serially connected in the stator line group of motor,, produce very high impedance from the impedance compensator starter in the moment of energising, make motor moment suffered voltage very low, electric current is very little, therefore, electric current is very little when switch closes a floodgate, basic no-spark appearance.
The utility model is simple in structure, and is in light weight, do not have empty cutting, and maintenance is convenient, and is reliable, is difficult for breaking down.
Describe the utility model in detail below in conjunction with embodiment shown in the drawings.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the cutaway view of iron core.
In Fig. 1 to Fig. 3, three iron cores 2 that have three garden shapes or rectangular steel tube to make are fixed between two block plates 3 side by side, are wound with coil 1 on each iron core 2, and the number of turn of coil 1 is the 25-40 circle.During use, before each coil of the present utility model sealed in the stator winding of three phase electric machine respectively, produce very high eddy current impedance at energising moment the utility model, make motor moment suffered voltage very low, starting easily, the utility model fault is few, without the asterism switch, so can there not be unloaded power consumption when sky cuts, starting time and autotransformer are basic identical in thread-changing, started, itself does not have.
