Description
Technical field
The utility model belongs to power domain, especially relates to a kind of secondary circuit transformation box.
Background technology
Along with the develop rapidly of national economy, electric load hits new peak repeatly, and electric network reconstruction is pushed open comprehensively, duration short task weight.For the vast power consumer of good service, ensure user's normal electricity consumption, in electric network reconstruction process, secondary circuit transformation is normally carried out when primary equipment does not have a power failure; The 3.7th article, People's Republic of China's power industry standard DL/T587-2007 " microcomputer protective relay device operational management code " regulation " service life of microcomputer protective relay device is generally 10-12 ".Protective devices a large amount of is at present near for useful life, protection remodel work and secondary circuit transformation work heavy.For ensureing personal equipment power grid security, clear stipulaties in " State Grid Corporation of China's electric power safety working regulation (power transformation part) ": forbid to open a way in secondary current loop.
Current secondary circuit safety measure is numerous, and general principle is as follows: one, indicating this secondary circuit is operating loop.Two, the anti-misoperation protective cover of protection pressing plate is adopted the pressing plate of misoperation can be caused to isolate miscarrying.Three, second loop return wiring terminal board short circuit plug is adopted to be shut by current circuit; Above scheme unresolved under machine operation to the following problem that faces in Substation secondary circuit transformation: 1, how to reduce expenses, effectively use original old cable; 2, for the transformer station that the time of putting into operation is long, secondary circuit drawing data incomplete or wrong time, how efficient lookup equipment secondary circuit, to shorten the transformation duration; 3, how to prevent dimension behaviour team staff from being opened by short good current circuit in equipment cleaning process out of doors by mistake; 4, on the equipment run, carry out secondary circuit (particularly poor to mother, malfunctioning loop) transformation, how to ensure in work progress that preventing bus differential protection or failure protection from moving causes transformer station's one section of bus even to cause transformer station's full cut-off, destroys power grid operation.
Utility model content
The utility model is the defect existed to solve above-mentioned prior art, and propose a kind of secondary circuit transformation box, its fail safe is high, has warning sign, avoids the cable of repetition to check investigation work, improves secondary circuit transformation operating efficiency.
Scheme of the present utility model is achieved in that
A kind of secondary circuit transformation box, it is made up of insulate mainboard and terminal board plug-in unit, it is characterized in that, described insulation mainboard is provided with and indicates box and deck, the yellow epoxy resin that described insulation mainboard is 8mm by thickness is made, and described sign box is made up of PVC transparent plastics, is provided with designation card in this sign box, described terminal board plug-in unit is made up of conductor pin and division board, and described division board is provided with warning sign.
Implement this secondary circuit transformation box of the present utility model, there is following beneficial effect: good insulation preformance, detachably, lightly portable, cheap, feature simple to operate; Indicating cable louding indication plate design in box can make staff move towards clear to cable, secondary circuit in improvement project, is convenient to secondary circuit transformation construction debugging; Be marked with " please don't extract " warning dimension behaviour team personnel at warning sign, ensure personal equipment power grid security; Deck ensures that box can firmly be fixed on terminal board, makes this box not only may be used for secondary circuit transformation engineering, can also warn this secondary circuit in running status in regular maintenance debugging.After transformation terminates, first extracted by terminal board plug-in unit, more just 4 decks unclamp, and namely take off secondary circuit transformation box from terminal board, next improvement project box is reusable.
Accompanying drawing explanation
Fig. 1 is this secondary circuit transformation box scheme of installation of the present utility model;
Fig. 2 is the decomposing schematic representation of Fig. 1;
Fig. 3 is terminal socket part schematic diagram in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Of the present utility model this secondary circuit transformation box as shown in Figure 1 to Figure 3, it is made up of insulate mainboard 4 and terminal board plug-in unit 3, described insulation mainboard 4 is provided with and indicates box and deck 6, deck is made up of electro-insulating rubber, deck enables box firmly be fixed on terminal board 5, makes this box not only may be used for secondary circuit transformation engineering, can also warn this secondary circuit in running status in regular maintenance debugging, the fixed form of transformation box, can also adopt the modes such as band is fixed, stickup.
The yellow epoxy resin that described insulation mainboard is 8mm by thickness is made, described sign box is made up of PVC transparent plastics, designation card is provided with in this sign box, indicating the design of recording the designation card of cable louding in box can make staff move towards clear to cable, secondary circuit in improvement project, be convenient to secondary circuit transformation construction debugging, especially at terminal board place, cable louding is indicated for the old station transformation that drawing data cable identification board is incomplete, avoid repetition searching work, improve work accuracy, shorten the transformation duration.Described terminal board plug-in unit 3 is made up of conductor pin 2 and division board 1, described division board is provided with warning sign, be marked with " please don't extract " warning dimension behaviour team personnel at warning sign, ensure personal equipment power grid security, in case terminal board plug-in unit is extracted personnel by dimension behaviour in equipment cleaning process by mistake.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
