Description
Technical field
The present invention relates to a kind of intelligent power distribution management equipment, and in particular to a kind of distribution becomes platform intelligent distribution box.
Background technology
With the fast development of power grid construction, low voltage network has also carried out large-scale construction and transformation, including line in recent years
Road insulating transformation, line footpath increase, become platform insulating, standardization etc..Greatly improve the reliability of low-voltage power supply.But become
Platform multifunctional distribution box is existing more than 10 years to since coming into operation, and does not obtain upgrading always, there is following safety and skill
Art is not enough.
First, with rapid economic development, in circuit (change platform) interruption maintenance, a large number of users (the especially bustling business in urban district
Industry area) it is lack of standardization generated electricity using house generator, electricity consumption.And it is existing with change platform multifunctional distribution box main switch after power failure
Will not division automatically, user's self power generation easily by its it is counter be sent on low-voltage distributing line, cause my electric power dimension, maintainer to touch
The generation of electrification.Now take precautions against method be exactly when having a power failure everywhere become platform all carry additionally ground wire, power construction people is significantly greatly increased
The labor intensity of member, while to such largely dress of ground wires, to tear management open be also great potential safety hazard in itself.
2nd, with main switch model is old, function is single in case.Short circuit or excessively stream are displayed without after fault trip, it is existing
Field, which robs maintainer, can not carry out complementary judgement accordingly.Casing is located at the sealing of case external insulation not with outside main power source tie point
It is good, easily intake or make moist oxidation, aging overheat, scaling loss.
The content of the invention
The present invention is located at outside case to solve existing distribution box body with outside main power source tie point, causes insulated enclosure not
It is good, the problem of oxidation of easily intaking or make moist, aging are overheated, and carry out interruption maintenance when, exist scene rob maintainer without
Method is matched somebody with somebody according to present field condition decision problem point, and then the problems such as the labor intensity of increase power construction personnel there is provided one kind
Electricity becomes platform intelligent distribution box.
Distribution becomes platform intelligent distribution box, including be fixed on the intelligent reset switch, intelligent controller, electric current of box house after
Non-electricity protector, controlling switch, earth protective device and metering current mulual inductor；The controlling switch connects with intelligent controller
Connect, intelligent controller is connected with intelligent reset switch, the intelligent reset switch is connected with metering current mulual inductor, the metering
Current transformer and electric current relay protector connection electric energy meter；The intelligent reset switch connection earth protective device, electric energy meter
Connection load；
The intelligent controller include accumulation power supply module, isolating transformer, detection module, cpu control circuit, from dynamic circuit connector
Lock driving, the driving of decompression automatic brake separating, combined floodgate IGCT and separating brake IGCT；The cpu control circuit respectively with accumulation power supply
Module, isolating transformer, detection module, automatic closing driving, decompression automatic brake separating drive connection；The accumulation power supply module point
It is not connected with detection module, combined floodgate IGCT and separating brake IGCT；It is primary that the combined floodgate IGCT and intelligent reset are switched
Coil is connected；The spare coil that separating brake IGCT is switched with intelligent reset is connected.
Beneficial effects of the present invention：Distribution of the present invention becomes platform intelligent distribution box and is retaining the former institute for becoming station power distribution case
It is functional it is constant on the premise of, using a kind of New Low Voltage automatic distribution switch, realize distribution line have a power failure when can disconnect automatically
Main power source, and charge circuit three-phase shortcircuit is grounded, to ensure that upkeep operation personal security is robbed in power supply.Effectively first is solved to ask
Topic.
In case intelligent control switch be aided with CT and control annex, loop realize have line fault overload, short-circuit protection and
Tripping operation identification display function, contributes to the live judgement processing of operation, repair personnel, reaches functions expanding.Intelligent reset is opened in case
Close and intend using unique operation mechanism and two independent arc-chutes, with disjunction arc extinguishing ability is strong, operation is reliable, small volume, machine
The features such as tool long lifespan.
Electrically (transformer secondary power supply) is connected using novel seal inserted sleeve, all insulation boundling casing with transformer
Formula bus.Insulating degree is higher, installs simpler and more direct.The easy aging overheat of power connection points, scaling loss can be prevented effectively from.Solving the
While two problems.General idea is to realize that installation lighter, function and technology content are more, insulating degree is higher, fortune
Row is more safe and reliable.Components above and sample product are detected after certification by doing type approval test after completing, carry out pilot
Using.
