Abstract
The utility model relates to a gauge cabinet, comprising a cabinet body and a current transformer and a voltage transformer in the cabinet body. The current transformer is an integration pouring type current transformer which is provided with an inlet wire terminal strip and an outlet wire terminal strip outside the cabinet body and is provided with a three-phase voltage electrode in corresponding connection with a primary lead between the inlet wire terminal strip and the outlet wire terminal strip in the cabinet body; the three-phase voltage electrode is connected to the voltage transformer on the bottom of the cabinet body by an insulating material integration pouring lead strip; the voltage transformer is formed by insulating material integration pouring. According to the utility model, the current transformer and the voltage transformer in the cabinet body and the lead strip used for connection are all formed by integration pouring; compared with air insulation of prior arts, the insulation distance of the utility model can be reduced so as to reduce a volume of the gauge cabinet.
Description
Technical field
The utility model relates to a kind of metering cabinet, belongs to the electric equipment field.
Background technology
Reliable in view of SF6 gas all-insulated switch device security, volume is little, safeguards plurality of advantages such as few, and along with the develop rapidly of China's electricity market, it send the application of electricity to increase year by year at distribution system ring network power supply and terminal.Typical characteristics of SF6 gas all-insulated switch equipment are exactly compact size, save and take up an area of the space.And metering cabinet mainly adopts air-insulated insulation mode, needs enough big insulation distance, so its volume seems huge than the switchgear of SF6 gas all insulation.Like Fig. 1 is traditional metering cabinet structure, and cabinet 5 tops are provided with turnover line terminals 1, and sidewall is provided with current transformer 4, connects the voltage transformer 3 of bottom through bonding conductor 2.
Metering cabinet is when using with SF6 gas all-insulated switch coordinative composition of equipments; Because the turnover line cap will be dielectric with the air; So bigger in the Width upper volume, the small and exquisite effect of SF6 gas all-insulated switch equipment volume will be had a greatly reduced quality, thereby have influence on the volume of whole primary equipment.Part manufacturer has adopted the way that CT, PT are concentrated in together, and this method has reduced the volume of metering cabinet, but because its difficulty of processing is big, manufacturing cost is high, and reasons such as installation inconvenience also can't well satisfy the demands.
The utility model content
The purpose of the utility model provides a kind of metering cabinet, and is bulky in order to solve existing metering cabinet, is difficult to the problem that cooperates with the SF6 gas-insulated switchgear.
For realizing above-mentioned purpose; The scheme of the utility model is: a kind of metering cabinet; Comprise cabinet and wherein current transformer and voltage transformer; Said current transformer is the one pouring current transformer, and this one pouring current transformer is provided with input terminal row and outlet terminal row outside cabinet, and this one pouring current transformer is provided with the three-phase voltage utmost point that is used for into and out of the corresponding connection of primary side lead between the line terminals row in cabinet; The said three-phase voltage utmost point connects the voltage transformer that is arranged on bottom of cabinet bulk through the lead row of insulating material one cast, and said voltage transformer is formed by the cast of insulating material one.
One is cast with three-phase secondary winding or A, C two phase secondary winding in the said one pouring current transformer.Said input terminal row and outlet terminal ranking are in an end of one pouring current transformer, and said voltage pole is positioned at the opposite end or arranges parallel two sides with said into and out of line terminals.All be arranged with sleeve pipe on each terminal of said input terminal row, outlet terminal row.Said sleeve pipe is the sleeve pipe of taper or band full skirt.
The metering cabinet of the utility model, the form of the lead of wherein current transformer, voltage transformer, connection usefulness being arranged equal one cast constitutes, and compares air insulation in the past, and its insulation distance can dwindle, thereby reduces the volume of metering cabinet.
