Brief description of the drawings
Fig. 1 is circuit structure diagram of the present utility model.
Specific embodiment
Utility model is described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, the utility model proposes dry type wide scope voltage-stablizer, including transmission line of electricity and central processing unit.
Live wire one end of transmission line of electricity is input voltage L1, and the other end is output voltage L2, is installed successively on transmission line of electricity
There is the first breaker HK1, main transformer TB1, secondary transformer TB2, the first A.C. contactor KM1, output current table and defeated
Go out voltmeter, the 3rd breaker HK3 is provided between main transformer TB1 and secondary transformer TB2, output voltage meter is used to detect
Voltage between output voltage meter, and the measurement circuit of voltmeter is provided with the second A.C. contactor KM2, central processing unit control
It is connected to the first breaker, the first A.C. contactor, the 3rd breaker and the second A.C. contactor.Central processing unit is connected to
The two ends of two A.C. contactor KM2.Central processing unit uses KWGD intelligent controllers（In Fig. 1 in dashed rectangle）,
The second breaker HK2 is additionally provided with transmission line of electricity, the second breaker two ends connect city's electric power system and defeated respectively
Go out ammeter, the second breaker is controlled to connect by the central processing unit.Central processing unit uses single-chip computer control system.It is secondary
Transformer is using the single-circuit transformer with the multigroup voltage of six taps.
During normal work, through electricity on breaker HK1 combined floodgates, output sampling transformer sampling is voltage signal for input voltage L1
To be sent to after control panel rectifying and wave-filtering become data signal through A/D conversions and be sent to central processor CPU and be analyzed to compare and send finger
Control relay is made to switch single-circuit transformer（Pair becomes）Tap voltage makes main transformer primary obtain relevant voltage to make use of transformer sense
Answering voltage superposition principle makes the voltage of main transformer secondary L2 change with main transformer primary voltage and change, so that output voltage is steady all the time
It is scheduled in range of set value；The time delay in the range of setting voltage of voltage regulation of cpu monitor output voltage sends signal control exchange for 5 seconds and connects
The voltage of tentaculum KM1 adhesives output stabilization；When output voltage because other reasons and failure make voltage beyond setting protection magnitude of voltage
When time delay send within 5 seconds signal cut A.C. contactor KM1 protection load end equipment and electrical equipment.
When voltage-stablizer breaks down is unable to voltage stabilizing, be manually operable by-pass switch HK2 be switched to city's electric position can be after
Continuous use does not influence power supply.
Above-described embodiment only expresses several embodiments of the present utility model, and its description is more specific and detailed, but simultaneously
Can not be therefore understands that being the limitation to the utility model the scope of the claims.It should be pointed out that for the ordinary skill people of this area
For member, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this reality
With new protection domain.Therefore, the utility model patent and protection domain should be defined by appended claims.
