Description
Technical field
The utility model relates to a kind of electrical test portable electronic pressure regulator.
Background technology
Pressure regulator is a kind of important electrical in electrical test, and common low capacity pressure regulator many employing contacts pressure regulation form, input end coil turn is fixed, and is changed the number of turn of output winding by slip device, reaches the object changing output voltage.The working method of pressure regulator many employings Induction Regulation that capacity is larger, changes primary and secondary coil coupling coefficient by the dynamic winding position of mobile self short circuit, thus adjustment output voltage.Experimental class goes out in test, and the three-phase contact type voltage regulator often used, rated capacity mostly is 10-15kVA.More than equipment self-weight 25kg, teams and groups arrange to need to carry pressure regulator go out test time, all want special arrangements two gay in vigorous health to be responsible for carrying pressure regulator.Certain interference is caused to the routine work arrangement of teams and groups.
Experimental class use the occasion of pressure regulator mainly in the withstand voltage test of insulating tool and transformer station the withstand voltage test of power equipment and Transformer Winding short-circuit impedance measure.The single-phase contact type voltage regulator of general employing in the withstand voltage test of insulating tool and power equipment, place capacity 10-12kVA; General employing three-phase contact type voltage regulator in test measured by Transformer Winding short-circuit impedance, place capacity 10-15kVA.
Measure in test at Transformer Winding short-circuit impedance, need pressure regulator and other surveying instrument to move near transformer, measure nearby.Test front equipment unload and test rear equipment loading time generally to account for the total Test time over half.Because equipment is comparatively heavy, pressure regulator needs 2 people to carry simultaneously, and walking is comparatively slowly its higher immediate cause consuming time.
In addition, testing ground exists that power supply is improper causes wiring comparatively complicated situation sometimes.Such as, needing the occasion of 380V, but only having the power for illumination of 220V nearby; When needing single-phase voltage to adjust in some cases, the neighbouring power electric but only having 380V, can not find 220V supply socket.
Summary of the invention
For solving above technical deficiency, the utility model provides one and is convenient for carrying, the electrical test portable electronic pressure regulator that work efficiency is high.
The utility model is realized by following measures:
A kind of electrical test portable electronic pressure regulator of the present utility model, comprise microprocessor, described microprocessor signals is connected with rectification circuit, IGBT buck circuit, IGBT boost chopper and inverter circuit, the voltage input end of described rectification circuit is connected with input line interface, IGBT buck circuit and IGBT boost chopper are in parallel and are connected between the voltage output end of rectification circuit and the voltage input end of inverter circuit, and the voltage output end of inverter circuit is connected with output line interface.
Above-mentioned microprocessor is connected with overvoltage crowbar.
The voltage input end of above-mentioned rectification circuit is connected with filtering circuit.
The beneficial effects of the utility model are: the adjustment that can realize voltage in the testing ground of situation complexity, and conscientiously alleviate pressure regulator weight, and convenient carrying, meets the integrated demand of experimental class to pressure regulator, improve the work efficiency of testing crew.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, further detailed description is done to the utility model:
As shown in Figure 1, a kind of electrical test portable electronic pressure regulator of the present utility model, comprise microprocessor, microprocessor signals is connected with rectification circuit, IGBT buck circuit, IGBT boost chopper and inverter circuit, the voltage input end of described rectification circuit is connected with input line interface, IGBT buck circuit and IGBT boost chopper are in parallel and are connected between the voltage output end of rectification circuit and the voltage input end of inverter circuit, and the voltage output end of inverter circuit is connected with output line interface.Microprocessor is connected with overvoltage crowbar.The voltage input end of rectification circuit is connected with filtering circuit.
Different from electromagnetic type pressure regulator, the chief component of electronic pressure controller weight is semiconductor devices and cooling system thereof.The composition of the electronic pressure controller of preresearch estimates 10kVA, the IGBT module weight of 50A is 200g, and main circuit needs 12 at the most, estimation main circuit general assembly (TW) is no more than 2.4kg, estimation cooling system 1kg, control system and casing estimation 1kg thereof, estimation general assembly (TW) is 4.5kg.Therefore, the 10kVA electronic pressure controller general assembly (TW) of development is no more than 5kg is feasible.Device is lighter, is applicable to single carrying.
According to the function logic frame chart determined, wherein, the function of overvoltage crowbar is ensureing on necessary overcurrent and overvoltage protection basis.Filtering circuit and rectification circuit mainly complete the filtering of import and export voltage, then convert alternating current to direct current, and when needs step-down, Microprocessor S3C44B0X IGBT buck circuit is connected, and realizes step-down.When needs boost, Microprocessor S3C44B0X IGBT boost chopper is connected, and realizes boosting.Eventually pass inverter the converting direct-current power into alternating-current power after pressure regulation is exported.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be considered as this patent.
