Multifunctional assembled anti-electricity-theft change platform batch meter
Technical field
The present invention relates to anti-electricity-theft field, the electricity-stealing prevention metering tank on especially a kind of transformer.
Background technology
It is a kind of electric power metering device of often using in the management of power use that transformer becomes the platform batch meter, especially for anti-electricity-theft, anti-electricity-theft extremely important on the transformer, carry out this work, key is to be equipped with relatively advanced batch meter, and become the platform batch meters with two kinds in market is example, and a kind of is transformer change platform batch meter based on iron batch meter; Another kind is the transformer change platform batch meter based on plastics system batch meter; In the majority with these two kinds.The former after installation, the one, near from the transformer high-voltage side, electric shock accidents takes place in poor insulativity, dangerous easily; The 2nd, operation conditions is not clear, and promptly the operation conditions of inner face ammeter and support equipment is difficult to observe the inconvenience of checking meter; The 3rd, not anti-electricity-theft because iron table case use be mostly common lockset, the back stealing of unblanking is difficult for finding with the back reduction; The 4th, easily to get rusty, serviceable life is short; The 5th, mode of connection is mixed and disorderly, and cabling is lack of standardization; The 6th, maintenance is inconvenient; The 7th, increased the wiring point of primary line, failure rate height; The 8th, summer, heat absorption was fast, temperature rise, the accuracy of influence metering; The 9th, can not adapt to multiple demands, realize installing flexibly; The tenth, can only walk lead, can not walk metal row, inapplicable to jumbo transformer.The latter such as Chinese patent ZL97204577.5 disclose a kind of substation transformer low-temperature measurement anti-electricity-theft device, it has compared tangible progress with iron table case, it includes cover base and the anti-encode seal that opens of antiforge laser holographic, has anti-stealing electricity function, its loam cake and base are formed casing, the low tension terminal of current transformer and substation transformer is in casing, mounting bracket is connected on its porcelain vase, and be fixed on the base, 4 anti-encode seals that open of antiforge laser holographic are on the involution around loam cake and the base, the backboard of facing the housing of wearing convex lens and being connected in the side of base is formed another casing, and the electric energy meter of outer cover heat shield is in this casing and be connected on the backboard; This batch meter is a plastic production, is increasing the service life, and there has been progress insulation, anti-aspect such as get rusty, but its cabling mode is the top outlet of base bottom or case, when cabling, need the bending outlet, the bending angle is big, outlet is not installed when the line footpath is big, particularly not can adorn metal row,, limit its usable range as aluminium row or copper bar etc., and complexity is installed, is not easy to the maintenance of transformer; Though also having designed the housing of band convex lens, it forms another casing with the backboard that is connected in the side of base, but it can not observe the joint wiring of transformer and the secondary connection position of batch meter, therefore, be difficult in time finding operating fault, thereby influenced the accuracy of the safe operation and the metering of transformer, integrated level is not high, can not accomplish to use for one the case more, function singleness, can not applied in any combination, thereby can not satisfy the needs of the different management mode of various places power supply department, greatly limited its usable range and practicality.
Technical scheme
The purpose of this invention is to provide a kind of multifunctional assembled anti-electricity-theft statoscope measuring tank that can select installation form according to user's needs.
Technical scheme of the present invention is achieved in that provides a kind of multifunctional assembled anti-electricity-theft change platform batch meter, and it is fastened by base member case and cover plate and constitutes the anti-electricity-theft guard box of a kind of low lamination shoe or it connects and composes a kind of anti-electricity-theft change platform batch meter by base member case and centerboard, back card/back board, front shroud, back cover; The low anti-electricity-theft guard box of lamination shoe is to be made of by being arranged on the plastic sealing base and the lock earhole fixing and locking that match on its both base member case and cover plate; The centerboard of described anti-electricity-theft change platform batch meter, back card/back board respectively with base member case on the centerboard groove of corresponding setting or back card/back board groove cooperate, install on the centerboard and install current transformer on voltameter, the back card/back board, back cover is contained on the base member case, after front shroud and base member case and back cover are connected and fixed, centerboard protrudes at the middle part of the casing of base member case and front shroud and back cover combination forming, is used for outlet; Narrate its usage below in conjunction with structure:
