Description
Technical field：
The invention belongs to electric and electronic technical field, and in particular to a kind of switching transformer type is without impact pressure regulator.
Technical background：
Due to the actual conditions of power distribution network, with region is scattered, supply line head the characteristics of, therefore when electric terminal often has peak of power consumption, voltage is low, it is big to fluctuate, and has a strong impact on power supply quality and reliability.
The content of the invention and beneficial effect：
This programme describes a kind of new-type auto-transformer on-load voltage regulation and adjusts the device that switching is combined with switch transformer, belongs to power supply technique.It can overcome the shortcoming of traditional auto-transformer type regulator, can reach switching without impact, loaded switch long lifespan, the advantages of regulation precision is high is particularly suitable for use in long distrbution network intelligent pressure regulating.
The technical scheme is that providing a kind of switching transformer type without impact pressure regulator, including Multiple coil auto-transformer TTK（Wherein public winding S1, tap-changing windings S2, control power supply winding S3）, on-load voltage regulating switch TQS, Current Transmit, voltage transformer pt, switch transformer handover module QH（Wherein switch transformer TK1, TK2, IGCT SCR1, SCR2）, controller PLC（Or other intelligent controllers）, it is characterised in that：Input switch transformer handover module QH through on-load voltage regulating switch TQS connections auto-transformer tap-changing windings S2 in without impact have load adjust by way of adjust voltage, and picked out in fixing end and be connected to output end, controller PLC by Current Transmit, voltage transformer pt（Or other intelligent controllers）Device outlet voltage, electric current are monitored by control power supply winding S3 for control electricity and using Current Transmit and voltage transformer pt, computing and the dynamic regulation for controlling on-load voltage regulating switch TQS actions to realize voltage.
Controller PLC（Or other intelligent controllers）The conducting controlling switch transformer handover module of control IGCT is monitored to each item data of power network makes two gear switch heads of on-load voltage regulating switch TQS keep no current state when switching gear respectively, ensure in gear switch without any impact, realize without impact pressure regulation.The characteristic isolated using switch transformer TK1, TK2 high-low pressure makes IGCT SCR1, SCR2 be placed in low-pressure end, and IGCT SCR1, SCR2 reliability service are ensured while control action is played.
Compared with auto-transformer on-load voltage regulation mode, increased switch transformer handover module, and on-load voltage regulating switch TQS is designed as two gear switch heads, make switch head during whole pressure regulation switch in the case of no current realize switching without impact, the design of two gear switch heads doubles regulation precision simultaneously, control power supply winding has inhibitory action using triangle connected mode to triple-frequency harmonics, the equipment is had the advantages that switching shock is small, regulation precision is high, loaded switch long lifespan, dependable performance stable.
