Description
Technical field
The utility model relates to a kind of capacitor, relates in particular to a kind of high-voltage parallel capacitor the complete sets of equipment.
Background technology
The raising requiring along with the develop rapidly of power grid construction with to the quality of power supply, high-voltage parallel capacitor the complete sets of equipment use more and more extensive, and be also on the increase according to the capacitor device demand that load variations compensation capacity can automatic switching cut type, for making compensation capacity more reasonable, capacity grouping is more and more especially, by original taking two groups as main be increased to present 4 groups even more.According between the indoor each mutually naked aluminium busbar of capacitor device standard-required 10KV and naked aluminium busbar need to be not less than the clear distance of 125mm between over the ground, so just cause because the inner bare bus bar quantity of packet type compensation arrangement cabinet is a lot, not only need very large bare bus bar arrangement space and installation and regular maintenance very inconvenient.
Chinese utility model patent (the patent No.: disclose a kind of high-pressure reactive compensation the complete sets of equipment 201220021065.0), comprise reactive power compensation branch road and controller, on three-phase bus, be connected in parallel to many reactive power compensation branch roads, it is characterized in that: described reactive power compensation is propped up route contactor, reactor, fuse and capacitor and is in series successively, described capacitor two ends all and connect discharge coil, described many reactive power compensation branch roads generally adopt wye connection, and described controller is electrically connected with many reactive power compensation branch roads.The beneficial effects of the utility model are: adopt many reactive power compensation branch roads access three-phase circuit in parallel respectively, can realize grouping automatic switching, according to voltage first principle, according to idle big or small automatic switching capacitor group, make system all the time in do not owe mend however mend, reactive loss minimum state, more than regulate voltage and electric current from motion tracking bus by controller, according to " nine district figure " automatically control packet contactor carry out that switching realizes.
This high-pressure reactive compensation the complete sets of equipment equally also exist structure relatively complicated, if for to controlling compared with multiple unit capacitor, require this device to have larger volume, thereby make troubles to assembling and setting.
Summary of the invention
For overcoming above-mentioned defect, the utility model technical issues that need to address: a kind of high-voltage parallel capacitor the complete sets of equipment are provided, and this apparatus structure compactedness is good.
For solveing the technical problem, the technical solution of the utility model: a kind of high-voltage parallel capacitor the complete sets of equipment, comprise some capacitor groups that are set together, and the compensation arrangement that these capacitor groups are controlled, compensation arrangement comprises cabinet, it is characterized in that, in cabinet, between components and parts, realizes connection by wire, the periphery of wire is enclosed with insulating barrier, at the fixed structure being upwards provided with for wire is fixed of walking of wire.This compensation arrangement is for controlling the capacitor group being connected in parallel, and described wire has formed flexible cable together with insulating barrier, and the full name of flexible cable is the copper core second third chlorosulfonated polyethylene sheath list core flexible cable that insulate.
As preferably, described fixed structure is the groove being arranged on cabinet wall body inner surface, and wire is embedded in groove.The trend of groove is preset, and wire along the trend of groove and be embedded in groove, can be determined these the complete sets of equipment distance between each wire in application process.
As preferably, described fixed structure is the pressing plate being arranged on cabinet wall body, and pressing plate is crimped on wire.Crimping by pressing plate to wire, and make the positional stability of wire in cabinet relatively better.
As preferably, described fixed structure comprises groove and pressing plate, and groove is arranged on the inner surface of cabinet wall body, and wire is embedded in groove, and pressing plate is fixed on cabinet wall body and is crimped on wire.This structure that presses solidly makes the positional stability of wire in cabinet good, and by setting in advance trend and the position of groove, makes between each wire in suitable distance.
As preferably, on described wire, there is bending, this radius bend is more than or equal to four times of insulating barrier external diameter.The least radius of this bending is four times of insulating barrier external diameter, when maximum radius, wire is on linear state, to the restriction of wire radius bend, make in the time that wire is arranged, even if wire has bending also can not bring too much influence to the electric conductivity of wire.
Therefore, the beneficial effects of the utility model: owing to being by realizing the electrical connection between components and parts with the flexible cable of insulating barrier, between each flexible cable, there is no the requirement of large distance, cabinet in compensation arrangement does not need too large, facilitated assembling and setting to compensation arrangement, the shared space of compensation arrangement is little.Also just because cabinet inside is without the need for too large headspace, compensation arrangement can be controlled multiple unit capacitor group, thereby makes these the complete sets of equipment can fully meet actual application demand.By the fixed structure that wire is fixed is set in cabinet, make the positional stability of wire in cabinet good, ensure the stability of these the complete sets of equipment work.
