Description
Technical field
The utility model relates to low-voltage distribution technical field, particularly a kind of servicing unit be applied in when breaker of plastic casing assembles.
Background technology
When the vertical forward of circuit breaker is installed or is laterally installed, make reference with the word of nameplate on circuit breaker panel or mark, using the end of incoming cables of the terminals above circuit breaker as power supply, have another name called power end, using the link of the terminals below circuit breaker as load, have another name called load end, this mode of connection, is called upper incoming line; Otherwise, the terminals above circuit breaker are used as load end, using the mode of connection that the terminals below circuit breaker use as power end, claim lower inlet wire.Circuit breaker line is generally upper wiring pattern, but often also because installing the demand of occasion, requires lower wiring patter wiring to circuit breaker.Such as: power supply is in the below of power distribution cabinet, electric power incoming line is more convenient to circuit breaker load end; Also have the upper and lower circuit breaker that two or two rows are housed in power distribution cabinet, electric power incoming line is introduced from middle part, connects upper and lower two or two circuit breakers arranged, then requires that circuit breaker adopts the mode of connection of lower inlet wire and upper incoming line respectively.Also have some special occasions, no matter adopt which kind of measure all to keep away the mode of unavoidable lower inlet wire, as some comparatively classical mother forms etc. in architectural electricity.
Adopt the breaker of plastic casing of lower inlet wire, at moving contact, after fixed contact disconnects, each phase moving contact connecting portion is electrified body, in one section of longer region, as alternate in the district that threads off have space, the electric arc produced during limit disjunction is because of the cause of electric power and arc control device position, although major part is extinguished in arc quenching system, but always there is the charged free gas of fraction to meet with adjacent phase electrified body, just phase fault may be produced, when limit short circuit breaking, arc control device are in below, producing thermal current direction during disjunction is upwards, arc chamber is entered to electric arc also unfavorable, destroy the normal disconnection of breaker of plastic casing.In addition, also have when circuit breaker upside-down mounting, because operator is accustomed to the general operation of circuit breaker, also very easily misoperation occurs.Specify by GB14048.2 " low voltage switchgear and control appliance low-voltage circuit breaker " standard: in the interrelated data that circuit breaker electric source and load end should indicate on nameplate or manufactory provides, so breaker of plastic casing generally only allows vertically or laterally to install, do not allow inlet wire under upside-down mounting.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can make that circuit breaker internal adopts conventional connections form, circuit breaker still adopts inlet wire upside-down mounting platform under the circuit breaker of vertical installment state.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
Inlet wire upside-down mounting platform under a kind of plug-in moulded case circuit breaker, comprise the mounting panel be vertically arranged in breaker of plastic casing shell, mounting panel is provided with the six roots of sensation side by side and vertical arrange swing to copper bar, the six roots of sensation swing to copper bar be that the A phase load be connected with load end above circuit breaker respectively swings to copper bar, B phase load swings to copper bar, C phase load swings to copper bar and be connected with power end below circuit breaker respectively A phase power supply swings to copper bar, B phase power supply swings to copper bar, C phase power supply swings to copper bar; The bottom that described A phase load swings to copper bar, B phase load swings to copper bar, C phase load swings to copper bar is respectively arranged with the load corresponding to circuit breaker internal load wiring terminal position and patches guide pillar, and the top that described A phase power supply swings to copper bar, B phase power supply swings to copper bar, C phase power supply swings to copper bar is respectively arranged with the connector guide pillar corresponding to circuit breaker internal power supply terminal position.
Improvement of the present utility model is: described B phase load is swung to copper bar and is connected on a mounting board with the two ends up and down that B phase power supply swings to copper bar respectively by reinforcing prop, described A phase load swings to copper bar, B phase load swings to copper bar, C phase load is swung to copper bar and form triangular structure form on mounting panel cross section, and described A phase power supply swings to copper bar, B phase power supply swings to copper bar, C phase power supply is swung to copper bar and form triangular structure form on mounting panel cross section.
Owing to have employed above technical scheme, acquired by the utility model, technological progress is as follows.
The utility model swings to copper bar by installing on a mounting board, the end of incoming cables (power end) of lower wiring patter is swung to leading-out terminal (load end), breaker of plastic casing still vertically formal dress state, do not change circuit breaker mounting means, do not change circuit breaker breaking capacity state under, realize inlet wire under power supply.The utility model is applicable to exchange in the distribution line of 50HZ, rated current 63A-630A, rated operational voltage 230V/440V, be convenient to use when needing breaker of plastic casing to realize lower wiring patter wiring to the distribution facility of alternating-current system and electric equipment, do not affect breaker of plastic casing overload, short-circuit protection performance; Simultaneously owing to have employed plug in construction, also facilitate safety inspection and the replacing of breaker of plastic casing.
