Abstract
Disclosed is a fixed metering cabinet of a metal armor draw-out switch device. The cabinet is a novel-style metering cabinet. A cabinet structure is divided into four independent cells comprising a bus bar cell, a CT cell, a PT cell and an instrument cell. Metal partitions are used for isolating the cells. A position where the bus bar passes through the cell is insulated by using an insulation sleeve. A metering PT and a metering CT are respectively fixedly disposed in the corresponding PT cell and the CT cell. The metering cabinet firstly overcomes problems that the metering PT is easily separated from a main circuit system. The metering cabinet meets the requirement that the metering PT is fixedly disposed, provides diversified selections and meets the requirement of combined cabinet usage with a high voltage switch device in a power distribution system.

The most frequently used switchgear is the metal enclosed structure of armored at present, cabinet and pull-out type parts (middle truck) two parts, consists of.Its electric energy metering cabinet scheme is to realize by the PT handcart with the cabinet of CT, and the mounting means of PT handcart wherein and the form of cabinet can be with reference to the switch metering cabinet schemes of announcing in Chinese patent 2012100918673.
This scheme is consistent with system equipment on version, but has some problems:
Metering PT is arranged on handcart, can advance or go out with handcart, and CT is fixedly mounted on cabinet.Because the metering PT of this metered scheme can be relatively easy to separate with main circuit system, so equipment measures of anti-stealing electricity imperfection.
Electric company is always very strict to the requirement of measuring equipment, and the requirement of various places electric company is inconsistent again, so such scheme is not local power supply department approval in a lot of places.
The utility model content
The utility model provides a kind of fixedly metering cabinet of metal armoring draw out switchgear, at first solves metering PT and can be relatively easy to the problem of separating with main circuit system; Meet the hard-wired requirement of metering PT simultaneously, a kind of diversified selection is provided, and the requirement of the high voltage switchgear in realization and distribution system cabinet use.
The technical scheme in the invention for solving the technical problem is: the fixedly metering cabinet of metal armoring draw out switchgear, and cabinet body structure is divided into independently compartment of four of bus-bar room, CT Room, PT chamber and control rooms; Between each compartment, adopt metal partion (metp) to separate, bus adopts the insulating sleeve insulation by the compartment place, and metering PT and metering CT are fixedly mounted on respectively in corresponding PT chamber and CT Room, and wherein CT is the abbreviation of current transformer, and PT is the abbreviation of voltage transformer.
Further, the mode that PT adopts fixing (can not extract out) to install, main bus bar also is connected with the bus of major loop in the mode of fixing (can not extract out).Install a vertical inner sealed board additional before the PT chamber, to meet the requirement of equipment " five is anti-".
Further, the employing package assembly of described cabinet, the cabinet material adopts the aluminizing zine plate, after digital control processing, with high-strength bolt, assemble, and door-plate and the shrouding corresponding with compartment be set respectively on the leading flank of cabinet and trailing flank, the door-plate of described cabinet and shrouding install lead sealing and hanging locking device additional, to meet user's needs.
The high overall dimension of the length and width of described cabinet is 800 * 1500 * 2300MM, consistent with the KYN28A metal armoring draw out switchgear, can meet the requirement that also cabinet is used in system.
Metering current mulual inductor (CT) adopts LZZJB9 series, and metered voltage instrument transformer (PT) adopts JDZ (X) 10 series, and LZZJB9 series, JDZ (X) 10 series are current version.
Preferably, described bus-bar room metal partion (metp) adopts the non-magnetic rustproof steel board.
The typical metered scheme that the utility model has solved the KYN28A metal armoring draw out switchgear passes the problem existed, and its effect is as follows:
1) solve metering PT and be easy to main bus bar system disengaging problem;
2) other stealing problems that are easy in the equipment use have been solved;
3) can realize using with KYN28A metal armoring draw out switchgear cabinet, meet the requirement of distribution system.
