Background technology
Electricity is the indispensable condition of scientific and technological progress, social development.Improving constantly of scientific and technological level, has had higher requirement to reliability, fail safe and purity for distribution.The properity of power supply and distribution facility is the important guarantee being related to for distribution quality.In low-voltage distribution cabinet used, just the switch disconnector of different capabilities, do not add on the crossbearer that is arranged on cabinet of shielding, pendulum order not science and footprint larger, connecting line disorder, has brought several weak points below like this; These connecting lines interlock as cobweb, unordered and chaotic, so not only assembly crewman has been proposed to high specialized capability requirement, and whole assembling process can only be completed by workman's link-up operation, cannot many people work simultaneously, more cannot continuous productive process, therefore, when manufacturability is poor, the quality of each switch cubicle is also because assembler's quality is different different; And whole assembly manipulation all will (after power distribution cabinet) complete after plate, operation inconvenience, and because contacting high pressure forceful electric power to poor stability; Element in power distribution cabinet is all to be matched by producer, and installation fixes, and user cannot select, poor expandability.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming, and a kind of good manufacturability, safe, easy to operate AC low voltage power switch box are provided.
The technical solution adopted in the present invention is AC low voltage power switch box, comprise cabinet, element, line, its structural feature is that it also includes electrical module, in cabinet, have the fixed strip of electrical module, electric mould comprises housing, element, and element is fixed in housing, electrical module is fixed on fixed strip, and electrical module is electrically connected by line.
Can in workshop, with standardization, normalization, mechanization, produce in batches like this, a workman only produces a kind of module, specialization in production, be conducive to improve quality, overall appearance is clean and tidy, and element is fixed in housing, without execute-in-place, not only improved quality but also raised the efficiency, in use can before plate, operate, before plate, safeguarded, wiring before plate, operating personnel, without contact high pressure forceful electric power, have improved fail safe, and user can combine installation according to the different module of need to selecting of oneself.Fixing hole in module can be long lumbar hole, so convenient installation.
The present invention also can be specially housing and be made by electric conducting material, the one side of housing is opening, and there is flange the fixing hole that has the lid matching with opening, two sides to have to match with fixed strip or the both sides of opening, on flange, have fixing hole, the upper and lower surface of housing has louvre.
All like this elements are all subject to electromagnetic shielding in module, element between module and module can not interfere with each other and affect work, and because its installing hole is all on surface, make installation, maintenance convenient and simple, the heat producing in the element course of work can distribute in time by louvre, to extend the useful life of element.
Electrical module generally all includes civil power access module, civil power total score electricity module, ups power output module, ups power and divides electric module, N.G.Zero-liue module, electrical quantity display module, these modules are that internet data central machine room is necessary, user also can be according to the module that need to select other function of oneself, as also having respectively or have emergency lighting and civil power alarm for power-off module, ATS double circuit power supply automatic switching module, SBP module etc. simultaneously, these modules respectively entirety are fixed on fixed strip, thereby versatility is good, applied widely.
The function of these modules is respectively: the Main Function of civil power access module is to introduce civil power to prevent load overload or short circuit, prevents thunderbolt; Civil power total score electricity module Main Function is with load, civil power to be distributed to every on demand directly to use civil power equipment, and prevent load overload or short circuit; Ups power output module Main Function is control and protect ups power output, and prevents load overload or short circuit; It is that ups power is distributed to each computer equipment and crucial power consumption equipment that ups power divides the Main Function of electric module, and prevents load overload or short circuit; N.G. the Main Function of Zero-liue module is civil power and ups power electrode, and ground wire is personal safe protection's contact, concentrates on a plate, convenient operation and maintenance; The Main Function of electrical quantity display module is to show real-time electric power operational factor, very clear being convenient to managed, generally can there be three frame pictures, can show in civil power UAB.UBc, UcA, IA, IB, Ic, Hz, P, COS and the output of UPS: Ua, Ub, Uc, h, Ib, Ic, Hz, P, COS in and direct voltage 1 totally 19 parameters, and can lead to RS232 interface and PC terminal communication, supervision real-time status and correction kernel parameter display are planted; The Main Function of emergency lighting and civil power alarm for power-off module is time illumination and give sound and light alarm signal for mains failure, is convenient to staff and processes in time; The Main Function of ATS double circuit power supply automatic switching module is when user adopts double loop input power supply, in order to guarantee the uninterrupted of power supply; The Main Function of SBP module is ups power maintenance bypass switch, guarantees the personal safety when UPS keeps in repair and the power supply to load.
Module width is 19 inches, can use height for two kinds of 30U, 40U, closes symbol international standard, thereby can carry out international.
The line of electrical module is all fixed on bus-bar, and the bus-bar fixed strip in cabinet is in the side of cabinet.Be convenient to wiring operation, safeguard.
The invention has the advantages that the component module in power distribution cabinet, making it can be with standardization in workshop, normalization, mechanization is produced in batches, overall appearance is clean and tidy, it is on-the-spot as long as each module is fixed in fixing hole and just can, not only improved quality but also raised the efficiency, in use can before plate, operate, before plate, safeguard, wiring before plate, operating personnel are without contact high pressure forceful electric power, improved fail safe, and in all modules, all there is electromagnetic shielding action, element between module and module can not interfere with each other, and because its installing hole is all on surface, make to install, easy to maintenance simple, the heat producing in the element course of work can distribute in time by louvre, extended the useful life of element.
