Problems solved by technology

The demarcation point of property rights is not clear, the meter reading inspection is inconvenient, and the outdoor metering device on the column has a relatively high failure rate due to poor operating conditions
Therefore, the power company stipulates that all metering cabinets (because most of the installation sites are cable lines, so metering cabinets must be installed) are invested by the power company, and the meters are directly installed in the metering cabinets, but there is no suitable metering cabinet on the market. , some manufacturers directly install the circuit breaker and metering device on the outdoor column directly in an outdoor box, and use it as a metering cabinet
However, there are many problems in this so-called metering cabinet: it is not safe for the operator to open the door to directly face the high voltage; Sealed, after long-term operation due to the occurrence of dust and condensation, insulation aging or even breakdown occurs; once a large flood occurs, facing the flood directly over the charged body, it is likely to cause personal safety problems; therefore, It is of great significance to develop a fully-sealed, fully-insulated, fully-sealed and fully-insulated 10kV metering cabinet with good safety and reasonable structure

Embodiment 1

[0017] Such as Figure 1-3 As shown, a fully sealed and fully insulated 10kV metering cabinet includes a cabinet body 5, incoming cables 2, and outgoing cables 4. The inside of the cabinet 1 is divided into four compartments by metal partitions, and the front is the operation interface , The cable inlet and outlet interface when left and right, the back is the metering interface, and the plug-in structure metering CT18 and PT cable 20 are arranged inside the cabinet 1.

[0018] In this embodiment, the outer shell of the entire metering cabinet is made of stainless steel, and the cabinet is divided into four compartments by metal partitions. The front is the operation interface, the cable inlet and outlet interfaces are left and right, and the back is the metering interface. The scope of responsibility of everyone is distinguished from the design structure, and mutual interference and wrangling are reduced. The metering CT and PT are under the metering interface. Both adopt plug-i...

Embodiment 2

[0020] Such as Figure 1-3 As shown, a fully-sealed and fully insulated 10kV metering cabinet includes a cabinet body 5, an incoming cable 2, an outgoing cable 4, the cabinet body 5 is connected with an incoming cable 2 and an outgoing cable 4, the incoming cable 2 is connected with a lightning arrester 1, the lower end of the cabinet 1 is provided with a grounding bar 3 for grounding, the middle position of the cabinet 5 is provided with a wing energy protection controller 6, and the upper end of the cabinet 5 is provided for manipulation The control structure panel 7, the cabinet 5 is divided into four parts: the outlet room 10, the instrument box 9, the cable room 12 and the air box 14. The outlet room 10 is provided with a plug-in metering CT18, and the outlet room 10 A PT cable 20, an outlet sleeve 22, and a three-phase integrated current transformer 23 are also provided inside. The cabinet body 5 is also provided with a mechanism compartment 13 which is provided with an i...

Abstract

The invention relates to a fully-sealed and fully-insulated 10 kV metering cabinet. The cabinet comprises a cabinet body, an incoming cable and an outgoing cable; an interior of the cabinet body is divided into four intervals by a metal partition plate; a front surface is an operation interface; left and right surfaces are incoming and outgoing interfaces of the cable; a back surface is a meteringinterface; the interior of the cabinet body is provided with metering CT (Current Transformer ) and PT (Post Tension) cables in a plug-in structure; the cabinet body is connected with the incoming cable and the outgoing cable; the incoming cable is connected to a lightning arrester; a lower end of the cabinet body is provided with a grounding bar for grounding; the middle position of the cabinetbody is provided with a wing energy protection controller; an upper end of the cabinet body is provided with a manipulation structure panel for manipulation, the cabinet body is divided into four parts of an outgoing room, an instrument box, a cable room and a gas box; the outgoing room is provided with a plug-in metering CT; and the outgoing room is further provided with a PT cable, an outgoing sleeve and a three-phase integrated current transformer. Therefore, the fully-sealed and fully-insulated 10 kV metering cabinet has the advantages of full sealing, full insulation, good safety and reasonable structure.

Description

Technical field [0001] The invention belongs to the technical field of power equipment, and specifically relates to a fully sealed and fully insulated 10kV metering cabinet. Background technique [0002] The metering cabinet is the main billing device between the power company and the user in the power system, and it is also particularly important as the demarcation point of property rights between the power company and the user. Most of the traditional electricity metering is invested by users, and the metering is realized by means of on-post switch with metering device. The meter and load control terminal of the power company are installed in metering equipment invested by the user. There are unclear boundary points of property rights, inconvenient meter reading and inspection, and the outdoor metering device on the column has a high failure rate due to poor operating conditions. Therefore, the power company stipulates that all metering cabinets (because the installation locat...
