Abstract
The utility model relates to a distribution transformer with an anti-stealing electricity function, which is additionally provided with a current mutual inductor, a current secondary wiring, a voltage secondary wiring and a multiple plug socket for electric energy metering on an existing distribution transformer. An electric energy measuring apparatus is additionally arranged. The utility model has simple structure, safe and reliable operation, and timely and accurate electric energy measurement. The electricity stealing behaviors between a low-voltage sleeve pipe of a transformer and a distribution room and on the pile head of the low-voltage sleeve pipe of the transformer can be completely stopped.
Description
The utility model belongs to a kind of anti-electricity-theft distribution transformer of electric power system controller switching equipment.
As everyone knows, distribution transformer is one of key equipment of electric power system.At present, the distribution transformer of extensive use only has the voltage transformation function, and electric energy survey metering device generally is located in the switchgear house.The shortcoming of this distribution transformer be can't prevent on the line between switchgear house and power transformation device low-tension bushing and transformer low voltage sleeve pipe pile crown on electricity filching behavior.A kind ofly electric energy is surveyed metering device directly be loaded on the outer distribution transformer of oil tank of transformer, can only effectively prevent the electricity filching behavior between switchgear house and transformer low voltage sleeve pipe, but can not prevent direct electricity filching behavior from transformer low voltage sleeve pipe pile crown; Owing to transformer the open air is set mostly again, thereby cost is higher, and the kilowatt-hour meter operational reliability is poor, checking meter, it is also dangerous to check.
At the defective and the deficiency of above-mentioned existing distribution transformer, the purpose of this utility model provides a kind ofly has that electric energy measurement function, power-steeling preventing effect are good, simple in structure, the anti-electricity-theft distribution transformer of safe and applicable.
Embodiment of the present utility model is: the current transformer that one group of coupling is installed on one's body at the device of existing distribution transformer; the multi-pin connector jack assemblies is fixed on the transformer cover plate; protective cover covers multi-pin connector; the electric current of electric energy metrical and voltage secondary circuit insert multi-core socket from current transformer and low-voltage lead, and multicore cable links to each other the electric power meter of multi-pin connector with the switchgear house inner sealing.
Now in conjunction with the accompanying drawings, technology contents of the present utility model is further described.Each that is loaded on transformer body respectively with one group of (3) current transformer (1) of distribution transformer coupling is mutually in the low pressure lead-out wire.Sidetracking at the distribution transformer cover plate has fixing hole (6), and multi-core socket (2) is packed in the fixing hole (6).Supporting multi-pin connector (3) links to each other with multi-core socket (2), and required electric current, the voltage secondary circuit of electric energy metrical drawn and inserted in the multi-core socket (2) by current transformer (1) and low-voltage lead.Protective cover (4) covers multi-pin connector (3), and multicore cable (5) links to each other the electric power meter of multi-pin connector (3) and switchgear house inner sealing.
In case distribution transformer work, current transformer (1) all can in time feed back to measurement loop with the transformer load current information, and what of institute's consuming electric power kilowatt-hour meter write down exactly.
The utility model is a kind of novel product, more can renovate on existing product.
Main feature of the present utility model is: 1, measure in time, stopped the electricity filching behavior of distribution transformer low-pressure side fully. 2, simple in structure, safe and reliable to operation, social and economic benefits and good. 3, applicability is strong, and application value is big, to function and the no any change of operation and the obstruction of existing distribution transformer.
Claims (1)
1, a kind of anti-electricity-theft distribution transformer, comprise current transformer (1), multi-core socket (2), multi-pin connector (3) and multicore cable (5), each that it is characterized in that being loaded on transformer body respectively with one group of (3) current transformer (1) of distribution transformer coupling is mutually in the low pressure lead-out wire; One sidetracking of distribution transformer cover plate has fixing hole (6), and multi-core socket (2) is packed in the fixing hole (6); Supporting multi-pin connector (3) links to each other with multi-core socket (2), and required electric current, the voltage secondary circuit of electric energy metrical drawn and inserted in the multi-core socket (2) by current transformer (1) and low-voltage lead; Protective cover (4) covers multi-pin connector (3), and multicore cable (5) links to each other the electric power meter of multi-pin connector (3) and switchgear house inner sealing.
