Abstract
A magnetic saturation motor voltage-regulating starter belongs to the technical field of starter, which comprises a variable reactor and a controller. Wherein, the variable reactor is composed of a variable reactor L1, a variable reactor L2 and a variable reactor L3, which are respectively connected between a power source and a motor in series. The controller is composed of a timer and a start indicator. The timer is composed of a time program controller IC6. Three pins of the time program controller IC6 are connected with a LED indicator light and a triode BG3 of the start indicator. The triode BG3 is connected with a contactor CJ. The contactor CJ is respectively is connected with the variable reactor L1, L2 and L3. The starter eliminates complex wiring, star connection and angular connection and only needs three input wires and three output wires, thus ensuring convenient onsite connection and greatly reducing failure rate. Load performance of the starter is remarkably superior to auto-transformer reducing starter and star and angular connection at present, thus preventing start failure and providing strong reliability, easy maintenance and long service life.
Description
Technical field
The utility model belongs to the starter technical field, particularly relates to a kind of magnetic saturation type motor pressure regulation starter.
Background technology
The widely used motor starter of China has following two kinds at present:
1, autotransformer reduced voltage starter.The design of this starter is in the short time operating state, and reduce voltage to motor after power supply a period of time with its excision, make motor be operated in the rated voltage state, its shortcoming is that load capacity is poor, heating is serious, the wiring complexity, maintenance is inconvenient.
2, star angle starter.The principle of this starter is when motor start-up, make motor work in the Y-connection state, changing triangle after a period of time into connects to enter under the rated voltage and moves, its shortcoming is, a, staring torque are little, its starting power only is 1/3 of a rated value, and is very unfavorable for the startup of heavily loaded motor, may not start motor sometimes.B, narrow application range, the motor that it is only applicable to that triangle connects and the disconnected son of wiring must phase-splitting be drawn.C, wiring complexity, external device is many, and the fault point is many, causes motor to owe to move mutually inconvenient maintenance easily.D, uncomfortable telemechanical are far controlled.
Summary of the invention
The purpose of this utility model is to provide the core circuit of a kind of one time of usefulness cyclelog as controller, controls variable reactor, utilizes the characteristic of variable reactor itself to finish the start-up course of different capacity motor.Wiring is simple, and on-the-spot easy to connect, load capacity is strong.In order to overcome disadvantages of background technology.
The utility model is by the following technical solutions: constitute magnetic saturation type motor pressure regulation starter by variable reactor, control.Its variable reactor is made up of L1, L2, L3, and they are connected on respectively between power supply and the motor; Controller is made of timer, startup indicating device, 3 pin that wherein constitute the program timer IC6 of timer are connected with the indicator light LED1, the triode BG3 that start indicating device, triode BG3 is connected with contactor CJ, and contactor CJ is connected with variable reactor L1, L2, L3 respectively.
Adopt above technical scheme, the wiring that this starter need not be complicated, the winding that does not also require motor is star connection or dihedral connection, only gets final product with three incoming lines, three output lines.On-the-spot connection is very convenient, and failure rate obviously reduces.Its load capacity is better than the autotransformer reduced voltage starter and the star angle starter of existing use greatly, and the failure phenomenon can not take place to start, and good reliability is easy to maintenance, long service life.
Description of drawings
Accompanying drawing 1 is the utility model syndeton schematic diagram.
Embodiment
Below in conjunction with accompanying drawing 1 and embodiment in detail the utility model is described in detail.
Embodiment of the present utility model such as accompanying drawing 1 are by variable reactor L1, L2, L3, compositions such as controller.Variable reactor L1, L2, L3 are the saturation type reactor, and it adopts no air-gap formula magnetic structure, guarantees its permanent reactance value under current state, in order to cooperate the start-up course of motor.The core of controller is program timer IC6, and its effect is the motor at different capacity, and the start-up course curve of motor is set, and reaches the purpose that starts the different capacity motor.Concrete syndeton such as accompanying drawing 1, variable reactor L1, L2, L3 independently are provided with, and are connected on respectively between power supply and the motor.Wherein variable reactor L1 one end is connected with power line A, and the other end is connected with motor D; Variable reactor L2 one end is connected with power line B, and the other end is connected with motor D; Variable reactor L3 one end is connected with power line C, and the other end is connected with motor D.Variable reactor L1 is connected with 1,6 pin of contactor CJ, and variable reactor L2 is connected with 2,5 pin of contactor CJ, 3,4 pin of variable reactor L3 and contactor CJ connect and compose the loop.
Controller is made up of program timer IC6, startup indicating device etc., as accompanying drawing 1, starts indicating device by triode BG3, resistance R 43, R44, and LED I forms.The base stage of triode BG3 is connected with resistance R 43, R44, and resistance R 43 is connected in series with LED 1.Wherein 3 pin of program timer IC6 are connected with the resistance R 43, indicator light LED1, the resistance R 44 that start indicating device, and resistance R 44 is connected with the base stage of triode BG3.The collector electrode of triode BG3 is connected with relay J OX-13F, diode D9, and the switch contact J1 of relay J OX-13F and contactor CJ is connected.2 pin of program timer IC6 are connected with capacitor C 11, resistance R 42, diode D8, and capacitor C 11, resistance R 42, diode D8 are connected on the control loop, 5 pin of program timer IC6 and capacitor C 12, and capacitor C 12 is connected on the control loop.
During motor starting, program timer IC6 discharges CJ, starter controller is constantly surveyed state of motor, when the state of motor is in starting state, make variable reactor L1, L2, L3 work in saturation condition, under the control of controller, its output current value remains on about 3.5 times of motor rated current, and motor is quickened and entry into service.The terminal voltage of motor is increased to 60% by zero, after reach 80% gradually again, reach 100% at last and enter steady operation.This moment, with variable reactor L1, L2, L3 short circuit, contacts of contactor switch J1 action put contactor CJ adhesive into operation by controller, indicator light LED1 flicker, and motor is finished starting process and is entered operating state.
