Abstract

The utility model provides a network control intelligent motor soft starter controlled silicon module device, which comprises a power phase input, an overvoltage trigger resistance, a controlled silicon anode, a controlled silicon cathode, a controlled silicon trigger electrode, a voltage regulator diode and a module output. One end of a filter resistance, one end of the overvoltage trigger resistance, and the controlled silicon anode are connected together and then are connected with the power phase input. One end of a filter capacitor is connected with the other end of the filter resistance.One end of the voltage regulator diode and one end of a diode are connected together and are connected with the controlled silicon trigger electrode. The other end of the voltage regulator diode is connected with the other end of the overvoltage trigger resistance. When the device works and the voltage between the power phase input and the module output is too high, the voltage regulator diode isconducted, the current reaches the controlled silicon trigger electrode through the trigger resistance and the voltage regulator diode, the controlled silicon is triggered and conducted, and then thevoltage of the controlled silicon is reduced so as to achieve the aim of protecting the controlled silicon.

Description

Network control intelligent electric machine soft starter silicon controlled module device
Technical field
The utility model relates to the silicon controlled module device, particularly a kind of network control intelligent electric machine soft starter silicon controlled module device.
Background technology
At present, adopt silicon controlled high pressure soft starter all to adopt the controllable silicon series circuit, each thyristor of this class circuit need be stabilized under the certain voltage works, if have an overtension can cause its voltage breakdown in each controllable silicon of series connection, it is simultaneously too high that other silicon controlled voltage is shared the back then, causes all controllable silicons of series connection all to damage at last.So make the reliability decrease of soft starter.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of simple in structure, long service life, safe and reliable soft starter silicon controlled module device are provided.
The technical scheme that the utility model network control intelligent electric machine soft starter silicon controlled module device adopts is: an end, controllable silicon anode that an end of filter resistance, overvoltage trigger resistance link together, and the connection power supply is imported mutually, one end of filter capacitor connects the other end of filter resistance, one end of controllable silicon negative electrode, an end of filter capacitor, link together and link block output, one end of voltage stabilizing didoe, an end of diode link together and connect the controllable silicon trigger electrode, and the other end of diode connects the triggering signal positive input.The other end that the other end of voltage stabilizing didoe and overvoltage trigger resistance links together.During device work, when power supply import mutually and module output between overtension the time voltage stabilizing didoe conducting, electric current by trigger resistance, voltage stabilizing didoe arrives the controllable silicon trigger electrode, triggers the controllable silicon conducting.So the voltage on the controllable silicon reduces, and has reached protection silicon controlled purpose.
The beneficial effects of the utility model are: working stability is applicable to digitization system, long service life.Simply, safety, reliable.
