Description
Technical field
The utility model relates to a kind of metering cabinet.
Background technology
Known; Metering cabinet cabinet inside generally is separated into bus-bar room, control room, measuring room, instrument transformer chamber and breaker chamber by dividing plate; Bus-bar room is positioned at cabinet upper strata, breaker chamber and is positioned at that cabinet lower floor, control room and measuring room are positioned at front side, cabinet middle level, the instrument transformer chamber is positioned at cabinet middle level rear side; The cabinet rear side is provided with by bus-bar room and draws and pass the copper bar that the instrument transformer chamber is connected with circuit breaker in the breaker chamber, be provided with in the instrument transformer chamber with the control room in the measurement instrument transformer that is connected of measuring instrument, with measuring room in the metering instrument transformer that is connected of metering device.
The cut-out of existing user's power supply is to accomplish through the circuit breaker in the breaker chamber, and can there be the situation of operate miss in circuit breaker in actual mechanical process, fails still to operate under the real situation of breaking off at circuit breaker, causes casualties; In addition for the generation of the leaky that prevents to sneak current; The instrument transformer chamber is equipped with the cabinet door that the user can not open voluntarily, though stopped to prevent the leaky of sneaking current like this, could open because of the instrument transformer chamber needs relevant departments; Bring inconvenience for like this maintenance and the dismounting of instrument transformer; Reduced maintenance and dismounting efficient, influenced user's normal electricity consumption, the maintenance and the dismounting of the measurement instrument transformer that particularly can not exert an influence to the electricity usage data.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, and a kind of simple in structure, safe and reliable metering cabinet is provided.
The purpose of the utility model realizes through following technical scheme;
A kind of metering cabinet with isolating switch; Comprise cabinet; The inner upper strata of said cabinet is provided with bus-bar room, lower floor is provided with breaker chamber; It is characterized in that: said cabinet inner middle layer front side is provided with the measuring room, the middle level rear side that are used to place the control room of measuring instrument and be used to place metering device and is provided with the instrument transformer chamber that is used to place instrument transformer; Said cabinet rear side is provided with from bus-bar room and draws and pass the copper bar that the instrument transformer chamber gets into breaker chamber, and said instrument transformer is provided with the isolating switch that is serially connected on the copper bar in the chamber.
Further, said isolating switch is serially connected on the copper bar of said instrument transformer chamber inlet wire side.
Further; Said instrument transformer chamber is separated into the metering instrument transformer chamber of arranging up and down and measurement instrument transformer chamber by dividing plate; Said isolating switch is arranged in metering instrument transformer chamber, and said metering instrument transformer is provided with the metering instrument transformer that is connected with metering device in the chamber, and is provided with the first cabinet door that the user can not open voluntarily; Said measurement instrument transformer is provided with the measurement instrument transformer that is connected with measuring instrument in the chamber, and is provided with the openable second cabinet door of user.
Further, the said first cabinet door is provided with the operating grip that matches with isolating switch.
The utlity model has following beneficial effect:
Be connected in series isolating switch on the copper bar in the instrument transformer chamber, when needs are cut off the electricity supply, adopt isolating switch to cut off simultaneously and the circuit breaker cut-out; Can guarantee like this under the situation of breaker operator error, guarantee that the circuit breaker front end is in electroless state, plays the effect of dual fail-safe; Effectively avoid casualties, when instrument transformer being overhauled or changing, need not to jump onto a grade switch like need; Jumping this cabinet isolating switch can realize, therefore reduces the power failure scope; The metering instrument transformer chamber and measurement instrument transformer chamber of mutual isolation are set at cabinet inner middle layer rear side; It is placed apart in two different chamber with the measurement instrument transformer to be about to measure instrument transformer; Because of the continuous data (electricity usage data) of metering instrument transformer to metering device can exert an influence; So be placed in the metering instrument transformer chamber and the cabinet that the user can not open be set, to stop the leaky of sneaking current; And be placed on the measurement instrument transformer that can not exert an influence to the electricity usage data measurement instrument transformer chamber and the openable cabinet of user is set, can be convenient to overhaul and dismounting measuring instrument transformer separately, thereby improve overhaul efficiency; Metering instrument transformer chamber is arranged up and down with measurement instrument transformer chamber; And copper bar is measured the instrument transformer chamber through metering instrument transformer chamber in process earlier; In time the user sneaks current from measuring instrument transformer chamber connection copper bar, and metering device also can accurately calculate power consumption, has further stopped the power stealing leaky.
