Embodiment 1

[0024] like figure 2 Shown is a schematic diagram of the assembly structure of the SF6 gas-insulated current transformer of the present invention. It is composed of gas storage cabinet UP100, variable diameter adapter shell flange LP200, foundation base BP300, and post insulator ZJ400.

[0025] In the present invention, the fixed connection scheme between the existing gas storage tank and the post insulator is changed from a large flat flange structure to a double-flange variable-diameter shell structure, that is, the variable-diameter adapter shell flange LP200, one end of which is connected to the gas storage tank The large end flange of UP100 is fixedly connected, and the other end is the small end flange fixedly connected with post insulator ZJ400. The current assembly scheme of the current transformer needs to first install the large flat flange on the gas storage cabinet, and then install the large flat flange on the post insulator. The installation structure is compli...

Embodiment 2

[0029] like image 3As shown, the structure schematic diagram of the current transformer gas storage cabinet UP100 of the present invention. It consists of connecting flange UP101, 2 outgoing terminal blocks UP102, 103, 2 lifting lugs UP104, 105, and explosion-proof plate UP106. The connecting flange UP101 is used for fixed connection with the flange LP200 of the variable diameter adapter housing; the outgoing line terminal base UP102, 103 is used for installing and rotating the outgoing line terminal; the lifting lugs UP104, 105 are used for the overall lifting and installation of the current transformer of the present invention; The explosion-proof disk UP106 is used to install the explosion-proof disk. If the internal pressure of the shell device increases sharply when a power failure occurs, the explosion-proof disk reaches the pressure limit and ruptures, and the internal pressure is released in time to avoid greater safety accidents.

Embodiment 3

[0032] like Figure 5 As shown, the structure schematic diagram of the flange LP200 of the current transformer reducing adapter housing of the present invention. The variable diameter adapter housing flange LP200 is used to replace the large flat flange of the existing current transformer. It is composed of a large end flange LP201, a small end flange LP202, and four internal component support seats LP203~206. The large-end flange LP201 is used to connect with the gas storage cabinet UP100, and the small-end flange LP202 is used to connect with the post insulator ZJ400, so as to realize the variable diameter transfer between the gas storage cabinet UP100 and the post insulator ZJ400, simplify the installation structure, and facilitate assembly operations Convenient; built-in component support base LP203-206 installs and fixes the built-in conductive components and supports.

Abstract

The invention relates to a gas storage cabinet device of a novel SF6 gas insulation current transformer. By changing a base assembly structure of an existing SF6 gas insulation current transformer, the application scheme of the current transformer in indoor assembly and performance detection is achieved; by extending an outgoing line terminal of a gas storage cabinet in the current transformer into the gas storage cabinet, the equipment volume is reduced, and the occupied area of a space is reduced; a connection part between the gas storage cabinet in the current transformer and a post insulator is changed to a dual-flange reducing shell-type structure used as a reducing conversion shell flange in a brand-new current transformer structure design scheme; according to a fabrication process of the gas storage cabinet device, the gas storage cabinet device is formed by integral casting and numerical control processing of aluminum alloy instead of processing an aluminum alloy plate; and the gas storage cabinet device simultaneously has functions of sealing and supporting the current transformer when used as a fundamental base in the brand-new current transformer structure design scheme.

Description

technical field [0001] The invention relates to a gas storage cabinet device, in particular to a novel gas storage cabinet device for an SF6 gas-insulated current transformer. Background technique [0002] As an indispensable device in the smart grid, the current transformer plays an important role in the operation of the smart grid. With the rapid development of the smart grid, the number of current transformers in the smart grid is also increasing exponentially. Current transformers are mainly oil-immersed current transformers and SF6 gas-insulated current transformers. The insulating medium of oil-immersed current transformers is insulating oil, and the insulating medium of SF6 gas-insulated current transformers is SF6 gas. Compared with insulating oil, SF6 gas has high insulation strength and has no environmental hazards under normal conditions. SF6 gas has excellent electrical insulation and arc extinguishing properties. The capacity is equivalent to 100 times that of...
