Abstract

The utility model relates to a feeder standardizing unit of a moulded case circuit breaker, which comprises an outer case, moulded case circuit breakers and a leakage sensor. A positive wire inlet bus bar is connected with a positive wire inlet bank of each moulded case circuit breaker. A negative wire inlet bus bar is connected with a negative wire inlet bank of each moulded case circuit breaker. A positive wire outlet bank and a negative wire outlet bank of each moulded case circuit breaker penetrate through the leakage sensor, and are led to the wiring terminals of a screen cabinet. The outer case is of a sealed box body. The positive wire inlet bus bar, the negative wire inlet bus bar, the moulded case circuit breakers and the leakage sensor are arranged in the outer case. The utility model provides a feeder standardizing unit of a moulded case circuit breaker, which has the advantages that the labor strength is reduced and the safety is enhanced.

Description

Breaker of plastic casing feeder line Standardisation Cell

Technical field

The utility model belongs to the parts of direct current cabinet, relates in particular to a kind of breaker of plastic casing feeder unit.

Background technology

Direct current cabinet is one of most important parts in electric power system generating and the electrical power trans mission/distribution system, and it provides continual operating power for power plant, transformer station, the contour low voltage switchgear of distribution substation and integrated protection automated system.It mainly reaches " system monitoring " etc. by " charger ", " storage battery ", " feeder line output " and forms." feeder line output " part of direct current cabinet generally has miniature circuit breaker feeder line output current to be generally less than 63A and the output of breaker of plastic casing feeder line according to the difference of size of current.

The breaker of plastic casing feeder line generally is made up of breaker of plastic casing, leakage current sensor, indicator light, connecting line and mounting structure spare, and traditional mounting means is to be fixed on sheet metal part on the rack by polylith to install and be connected, and labour intensity is big; In screen is the structure of open type, and this has just caused inner connection copper bar and lead to leak outside, and brings danger for the maintenance of system.In addition, because wiring is more, aesthetic property and regularity in causing shielding descend.

Summary of the invention

For dangerous high, the big deficiency of installation labour intensity of the breaker of plastic casing feeder unit that overcomes existing direct current cabinet, the utility model provides a kind of breaker of plastic casing feeder line Standardisation Cell that improves fail safe, reduces labour intensity.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of breaker of plastic casing feeder line Standardisation Cell, comprise shell, breaker of plastic casing and leakage current sensor, anodal inlet wire busbar is connected with the anodal lead-in line row of each breaker of plastic casing, negative pole inlet wire busbar is connected with the negative pole lead-in line row of each breaker of plastic casing, the anodal outlet row of each breaker of plastic casing and negative pole outlet row pass leakage current sensor and lead to screen cabinet binding post, described shell is an enclosed housing, and described anodal inlet wire busbar, negative pole inlet wire busbar, breaker of plastic casing and leakage current sensor are positioned at shell.

As preferred a kind of scheme: described enclosed housing comprises door-plate, left plate, right plate, upper cover plate, lower cover and back shroud, described left plate is fixedlyed connected with the chassis with right plate, described upper cover plate, lower cover and back shroud are all fixedlyed connected with right plate with left plate, described door-plate right side and right plate are hinged, and door lock is installed in described door-plate left side.

Further, the casing of described door-plate both sides is provided with hangers, and described hangers is provided with the installing hole that is used for the installation of rack cabinet.

1), fail safe improves the beneficial effects of the utility model mainly show:: owing to adopt enclosed construction, reduce live part bare areas such as copper bar greatly, reduced personnel's probability that gets an electric shock in regular job with when safeguarding.2), technology is attractive in appearance: enclosed construction is enclosed in element and wiring in the casing, makes that whole screen cabinet is neat, technology is elegant in appearance.3), plug-in modular structure: be convenient for changing, mould shell short-circuiting device feeder unit and adopt the plug-in modular construction, each unit can be replaced mutually.4), reduce producers' labour intensity.The conventional mounting mode needs producers at screen cabinet back panel wiring, and personnel install before need standing in the screen cabinet for a long time, and labour intensity is big.And modularized design can make producers on workbench the breaker of plastic casing feeder unit be assembled, and refills the screen cabinet at last.5), save the space:, more save the space than original open type installation because inside has adopted degree of integration than higher mounting means.
