Description
Technical field
The invention belongs to electric power overhaul field, and in particular to portable multi-function is adjustable alternating current-direct current power box for high tension testing.
Background technology
Transformer station carries out that experiment power supply need to be accessed when electrical test and repair and maintenance, and transformer station typically only has quantity in outdoor
Seldom（Even without）Power connection be available for accessing, it is therefore desirable to a fairly large number of power supply box carries out connection in series-parallel and integrates and could accord with
The electricity consumption requirement of site examining and repairing is closed, for remoter scene, external power supply is distant, cable length 50m power supply box
Live needs can not still be met, be inconvenient；House generator is needed to be generated electricity when running into whole station interruption maintenance, and generator
Volume mass it is bigger than normal not readily transportable, and the quality of power supply does not reach requirement, there is the risk of damage precision instrument.
Transformer station's new clothes and replacing protection device task are heavy, and it is big that scene obtains dc source difficulty.Traditional work
Mode is to guide to protection screen from experiment power supply screen by interim long wire or cable, and accident of human electric shock easily occurs, dangerous
Greatly.
Under existing condition of work, 220 volts of alternating currents are only fixed, can not be standby to new clothes protection device without direct current
Part carries out functional test.Product spare part standing time is grown, and can not judge whether it meets onsite application.Meanwhile under working environment,
Lack necessary experiment power supply, spare part quality can not be verified.If be unsatisfactory for, protection staff will be caused to come and go scene, caused not
The necessary wasting of resources.
In addition, existing power supply box be other equipment power, it is necessary to voltage type, current type, voltage or electric current
Size has specific requirement, and existing power supply box can not meet the test request of plurality of devices so that application is by very big
Limitation.Protection equipment power insert is once changed for every 5 years, is changed more frequent；Whether relay spare part meets that scene makes
With situation, this is required for going to test by power of alterating and direct current.
There are some power supply boxs in patent document disclosed in prior art.
Notification number is that CN2153167Y patent document discloses a kind of Multifunction hand power box with alternating current-direct current output,
It has socket, charge switch, transformer, control circuit so that power supply box has the functional structure that alternating current-direct current is inputted and exported.
Above-mentioned patent function is single, can not meet the needs of multiple voltage and electric current, and does not have regulatory function, it is impossible to right
The new clothes protection device such as relay spare part carries out functional test, finds the problem of spare part there may be in advance, avoids security incident
Generation and reduce the wasting of resources.
The patent document that notification number is the U of CN 203553979 discloses mobile integrated power box for high tension testing, moves handcart, if
Casing on mobile handcart bottom surface, the air vent and handle being respectively provided on casing left side plate, is located on casing front panel
Charging socket, constant pressure source controlling switch, constant pressure source output interface, constant-current source controlling switch, constant-current source output interface, voltmeter
Controlling switch, inverter control switch, multifunctional power socket, D.C. voltmeter and monitoring form is exchanged, and the lithium being located in casing
Ion accumulator, inverter, constant-current source, constant pressure source and earth leakage protective device；Lithium-ions battery connects charging socket, while lithium
Ion accumulator connects D.C. voltmeter by voltmeter controlling switch, and switchs connection inverter by inverter control；It is inverse
Become device and multifunctional power socket is connected by earth leakage protective device, while inverter connects constant-current source by constant-current source controlling switch, and lead to
Cross constant pressure source controlling switch connection constant pressure source；Constant-current source connects exchange monitoring form simultaneously and constant-current source output interface, constant pressure source are same
When connection exchange monitoring form and constant pressure source output interface.The comprehensive power of the power supply box provides power supply by battery, by inversion
After be supplied to conventional insert row to supply 220V AC powers, pass through pressure regulator element constant current be provided and exchange 2A power supplys and constant voltage DC
12V voltages.Each electrical equipment is controlled by corresponding controlling switch, and has voltage, ammeter monitoring, and casing both sides set handle, and
Radiated provided with ventilating opening, casing is connected with portable handcart, facilitates power supply box movement to carry.
Anywhere above-mentioned patent can provide the alternating voltage needed for experiment and lead to similar to mobile phone charging portable power source
Electricity, beat alternating current and DC voltage needed for polarity, portable power source limits in other areas but similar mobile phone charges
Application, technology barrier can not be overcome.
The voltage and current of offer is single, too small, it is clear that can not meet that electric power overhaul field is set to electric power in the prior art
Standby needs, and there is no regulatory function, it is impossible to functional test is carried out to the new clothes protection device such as relay spare part, is found in advance
The problem of spare part there may be, the generation for avoiding security incident and the reduction wasting of resources.If galvanic current source be present, entering
The old screen of row is taken out stitches carries out the debugging efforts of new clothes protection device with the cable laying stage in advance, and just can be that protection device is secondary connects
Loop transmission after line provides abundant test period, ensures the correctness in loop, it is horizontal to improve power grid security O＆M.
