2) parameter voltage stabilizing technique
It is to utilize non-linear element that the voltage and current in the circuit is adjusted, and realizes output voltage stabilization.Its advantage is that circuit is simple, the precision of voltage regulation high (± 1%), and antijamming capability is strong, and voltage stabilized range is wide.Its shortcoming is that non-linear element is responsive to operating frequency, also power consumption when unloaded, and temperature rise is serious.
3) inductive compensation type voltage stabilizing
It is to utilize the elementary winding of servomotor control drive disk assembly and the compensation winding of static component to form.Its advantage is fricton-tight contact, and is reliable.Its shortcoming is with servomotor control, bad dynamic performance, and center line might be charged when the input three-phase imbalance in addition, even big electric current occurs.
4) contactless compensation automatic voltage regulator
The main distinction of it and above-mentioned 3 kinds of compensated voltage regulators is on " compensation " method.The voltage-regulating system of contactless offset-type automatic voltage regulator is " a multi-channel compensating system transformer group get on well with others body "; Through " the multichannel full bridge power circuit break-make of controlling a plurality of noncontacting switches obtains positive and negative bucking voltage, and whole bucking-out system is contactless, does not have mechanical transmission; thus improved reliability of operation greatly; response speed, precision, voltage stabilized range etc.
Summary of the invention
The purpose of the utility model is to the deficiency of existing alternating current steady voltage plug existence the new automatic alternating current steady voltage plug that a kind of input range is wide, contactless, precision is high to be provided.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of new automatic alternating current steady voltage plug; Form by compensation transforming circuit, voltage sensor, current sensor, temperature sensor, control module; Voltage sensor, current sensor and temperature sensor all are connected with control module, and control module is connected with the compensation transforming circuit.
And described compensation transforming circuit is made up of many compensator transformers, becomes contactless unit with solid-state relay group.
And described many compensator transformers are selected the platform number of transformer according to the precision of voltage regulation and the area requirement of input power supply.
And described compensator transformer assembled unit is made up of the power full-bridge circuit that some solid-state relays and compensator transformer are formed respectively.
The advantage and the good effect of the utility model are:
1, main circuit has been avoided surge and High-frequency Interference through the zero voltage switching of solid-state relay, and voltage stabilized range is wide, and load regulation is wide, and dynamic response is fast.
2, on main circuit, installed the filter of various models additional; Can prevent various interference, and high-quality surge protector is installed to have anti-thunder and lightning wave resistance and gush function; Also (inductive load is big) can be joined the automatic power factor bucking-out system as required, and compensation back power factor can reach 99%.
