Abstract
The utility model provides an energy-saving PTC starter. A PTC element is connected in series with a bidirectional controllable silicon; a bidirectional trigger tube D1, a resistance R1, a capacitance C1 are connected in series between a gate electrode G of the bidirectional controllable silicon and an A2 pole, in order to form a gate trigger loop. A bidirectional switch consisting of a bridge D2 and a triode T1 is connected in parallelism on a bidirectional controllable silicon A1 pole and the bidirectional trigger tube D1. When the electricity is started to be got through, the bidirectional switch is not conductive, and the bidirectional controllable silicon is conducted by the current in the gate electrode trigger loop; meanwhile, the capacitance C2 is started to be charged. When the voltage of the capacitance C2 is risen to cause the triode T1 to be conducted, the bidirectional switch is conducted, and the gate electrode trigger current of the bidirectional controllable silicon is changed non-conducted by a bypass bidirectional controllable silicon, the main circuit current is cut off, and the PTC element does not heat, thus reaching the energy-saving object.
Description
Technical field
The utility model relates to a kind of PTC starter, is mainly used in the starting of monopole asynchronous motor, has energy-conservation characteristics.
Background technology
The present PTC starter that generally uses, the PTC element is in the heating power state always and produces higher energy consumption in the motor course of work.This is a major defect of PTC starter.
The utility model content
In order to overcome the above-mentioned shortcoming of PTC starter, the utility model provides a kind of energy-conservation PTC starter.
The technical solution of the utility model is: the PTC element connected with a bidirectional triode thyristor, and bidirectional triode thyristor conducting when beginning to switch on, starting current is by the PTC element, and the electric current by the PTC element after starting is finished is turn-offed by bidirectional triode thyristor, reaches purpose of energy saving.Insert the A2 utmost point of bidirectional triode thyristor after the gate pole G of bidirectional triode thyristor connects with two-way trigger tube D1, resistance R 1, capacitor C 1, form gate pole and trigger the loop.The bidirectional switch of forming by bridge heap D2 and triode T1 in parallel on the bidirectional triode thyristor A1 utmost point and two-way trigger tube D1.When beginning to switch on, the not conducting of described bidirectional switch, the gate pole that triggers the current direction bidirectional triode thyristor in loop by described gate pole makes the bidirectional triode thyristor conducting, and simultaneously, circuit begins to capacitor C 2 chargings by current limiting element R2, diode D3.When the voltage on the capacitor C 2 rises to when making triode Tl conducting, described bidirectional switch conducting, the gate pole triggering signal of described bidirectional triode thyristor is by bypass, the electric current of C1, R1 of flowing through no longer flows to the gate pole of described bidirectional triode thyristor, but flows to described bidirectional switch, therefore, described bidirectional triode thyristor becomes not conducting, the electric current of PTC element of flowing through is turned off, and the PTC element is heating power no longer, reaches purpose of energy saving.
The beneficial effects of the utility model are: the energy consumption that reduces the PTC starter.
