Description
Technical field
This utility model is related to power transmission and distribution and arranges detection technique field, more particularly to a kind of for the secondary confession of electricity substation
Electric system auxiliary equipment.
Background technology
At present, the load equipment in existing Power Secondary electric power system is connected to as power supply unit by drive module
Outfan, the alternating current or unidirectional current by needed for the alternating current that power supply unit is provided is converted to load equipment by the drive module,
Thus reach the control to load equipment.Due to when lightning current is excessively powerful, there is fraction thunder and lightning to flow into load
Equipment, causes load equipment to damage ring under the impact of thunder-strike current residual voltage.
The content of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model to be to provide a kind of for the secondary confession of electricity substation
Electric system auxiliary equipment.
For achieving the above object, this utility model is employed the following technical solutions：
It is a kind of to be used for the secondary electric power system auxiliary equipment of electricity substation, two between power supply unit and load equipment
Lightning circuit is connected between the input and earth terminal of secondary electric power system auxiliary equipment；The output of secondary electric power system auxiliary equipment
Lightning circuit is connected between end and earth terminal；Secondary electric power system auxiliary equipment is by rectification circuit, power adjusting circuit, inversion electricity
Road, microprocessor composition, rectification circuit is connected with inverter circuit by power adjusting circuit, power adjusting circuit and microprocessor
Adjustment end be connected, the control end of microprocessor is connected with inverter circuit；The data transmission terminal of microprocessor is connected with touch screen.
There is advantages below due to adopting technical scheme as above, this utility model：
It is a kind of to be used for the secondary electric power system auxiliary equipment of electricity substation, enable to into the thunder and lightning residual voltage for loading more
It is little, desirably prevent load to be struck by lightning, improve its safety in utilization, extend its service life.And strong interference immunity.With work
Make reliable, the characteristics of make simple, high safety.
Description of the drawings
Fig. 1 is the circuit diagram block diagram for the secondary electric power system auxiliary equipment of electricity substation.
Specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.
As shown in figure 1, a kind of be used for the secondary electric power system auxiliary equipment of electricity substation, set positioned at power supply unit and load
Lightning circuit is connected between the input and earth terminal of the secondary electric power system auxiliary equipment between standby；Secondary electric power system is attached
Lightning circuit is connected between the outfan and earth terminal of device；Secondary electric power system auxiliary equipment is adjusted by rectification circuit, power
Circuit, inverter circuit, microprocessor composition, rectification circuit are connected with inverter circuit by power adjusting circuit, power adjustment electricity
Road is connected with the adjustment end of microprocessor, and the control end of microprocessor is connected with inverter circuit；The data transmission terminal of microprocessor
It is connected with touch screen.
For the use of the secondary electric power system auxiliary equipment of electricity substation：The alternating current power supply of power supply unit passes through rectified current
Road rectification is converted to unidirectional current alternating current；Using circuit of power factor correction make input current be close to sine wave, reduce electricity
Net harmonic content, realizes improving the purpose of power factor；Using inverter circuit be complete unidirectional current to three-phase alternating current turn
Change, realize frequency modulation and voltage modulation purpose；
When touch screen sends signal, the work of circuit of power factor correction and inverter circuit is controlled；Produce three-phase modulations ripple
Shape, output voltage is adjustable, the three-phase alternating current of changeable frequency, for the motor of load equipment, so as to realize the electricity to load equipment
Machine carries out stepless frequency control control.
