Abstract
The invention discloses a full-insulation annular net cabinet metering unit which comprises a cabinet body, a voltage transformer, a copper bar and a fuse, wherein the voltage transformer is arranged in the cabinet body and is positioned below the cabinet body; the copper bar is arranged in the cabinet body and is positioned above the cabinet body; the fuse is arranged between the voltage transformer and the copper bar; and the copper bar is also connected with an expansion casing which adopts a lengthening crank arm. The electrical clearance issue of a 10kV full-insulation cabinet metering unit is solved well, electrical accidents caused by aging materials or material deformation during the using process can not be generated, and the running of the 10kV full-insulation annular cabinet metering unit in a safe environment is ensured.
Description
Technical field
The present invention relates to a kind of all-insulated ring network cabinet metering units.
Background technology
The 10kV all-insulated ring network cabinet begins extensive use in electrical network, the metering cabinet unit of using in the circuit system is because must be supporting with all insulation cabinet of other circuit units, inherent characteristics because of all insulation cabinet, the arrangement centre distance of bus is generally below 130mm, electric clearance between bus and the bus only has about 80mm, can't satisfy the above requirement of 125mm of standard.Now the modes of the supporting most employing of metering units isolating shrinkable tube reinforced insulation are finished with it, meet the demands reluctantly.Owing to heat-shrink tube can occur aging in used process or can't well solve because the bus temperature rise causes the insulating case distortion can't satisfy the shortcoming such as insulating requirements so that insulating capacity descends.
Summary of the invention
Main purpose of the present invention is to provide a kind of safe and reliable all-insulated ring network cabinet metering units.
For addressing the above problem, the present invention adopts following technical scheme: a kind of all-insulated ring network cabinet metering units, comprise cabinet, and be arranged on voltage transformer in the cabinet and that be positioned at the cabinet below, and be arranged on copper bar in the cabinet and that be positioned at the cabinet top, and be arranged on fuse between voltage transformer and the copper bar, and described copper bar also is connected with the expansion sleeve pipe, and the expansion sleeve pipe is to have adopted the expansion sleeve pipe that lengthens connecting lever.
Further, a side of described copper bar is provided with current transformer, and the another side is provided with insulator.
Further, also be provided with insulator in the described current transformer.
The beneficial effect of all-insulated ring network cabinet metering units of the present invention is: well solve the electric clearance problem of 10kV all insulation cabinet metering units, can not produce the electric accident that causes because of material ageing or distortion in the process of using.Guarantee that 10kV all insulation ring cabinet metering units moves under the environment of safety.
Description of drawings
Fig. 1 is the schematic diagram of all-insulated ring network cabinet metering units of the present invention.
Embodiment
See also shown in Figure 1, a kind of all-insulated ring network cabinet metering units of the present invention, comprise cabinet 1, and be arranged on voltage transformer 2 in the cabinet 1 and that be positioned at cabinet 1 below, and be arranged on copper bar 3 in the cabinet 1 and that be positioned at cabinet 1 top, and be arranged on fuse 4 between voltage transformer 2 and the copper bar 3, and described copper bar 3 also is connected with expansion sleeve pipe 5, and expansion sleeve pipe 5 is to have adopted the expansion sleeve pipe that lengthens connecting lever.
One side of described copper bar 3 is provided with current transformer 6, and the another side is provided with insulator 7.Also be provided with insulator 7 in the described current transformer 6.
10kV all-insulated ring network cabinet metering units adopts special existing in the process of installing with the expansion sleeve pipe 5 that lengthens connecting lever with the sleeve pipe that is connected of all insulation cabinet, utilize the effect of connecting lever, distance of installation bus of each expansion sleeve pipe 5 guaranteed the distance that requiring, the expansion sleeve pipe 5 that adds connecting lever adopts epoxide resin material, have anti-aging, the characteristics such as shape is fixing.
Because the metering units of the full hoddy ring main unit of 10kV has adopted the expansion sleeve pipe 5 that lengthens connecting lever, in use can not produce distortion, the electric clearance after guaranteeing to install can satisfy the requirement of regulation, so that its body knowledge is less, and safety and reliability.
The beneficial effect of all-insulated ring network cabinet metering units of the present invention is: well solve the electric clearance problem of 10kV all insulation cabinet metering units, can not produce the electric accident that causes because of material ageing or distortion in the process of using.Guarantee that 10kV all insulation ring cabinet metering units moves under the environment of safety.
The above be the specific embodiment of the present invention only, but protection scope of the present invention is not limited to this, and any variation or replacement of expecting without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claims were limited.
