Description
Technical field
The present invention relates to a kind of electronic trip unit that is installed in the low-voltage circuit breaker, relate in particular to the support of the instrument transformer in the fixing electronic trip unit.
Background technology
Low-voltage circuit breaker is commonly used has the distribution type, protect electronic type, band residual current protecting type and electronic breaker.Electronic low pressure circuit breaker has overload long delay, short circuit short time delay, short circuit is instantaneous and function such as under voltage protection, and is more comprehensive than common circuit breaker on the function, and distribution line and electric equipment are played more reliable protection; The various functions of electronic type all rely on electronic trip unit to realize; Electronic trip unit comprises: instrument transformer, circuit board and executive component; The every utmost point of circuit breaker all has an instrument transformer to detect the current situation that flows through circuit breaker in real time; Instrument transformer is little current signal with big electric current conversion and is delivered to the treatment circuit plate, the instruction process signal that circuit board configures according to the user, and whether the indication executive component moves.The instrument transformer of present electronic breaker generally directly navigates in the stopper slot that base cooperates with it, thereby on base, is provided with many position limiting structures that cooperate with instrument transformer, and its defective is to make base complicated.The all leaded circuit board that is connected to of arbitrary instrument transformer, existing mounting means makes cabling confusing, connects not location of lead, and lead is damaged and runs into easily the major loop of circuit breaker easily when assembling, cause the potential safety hazard of circuit.
Summary of the invention
The purpose of this invention is to provide a kind of electronic transducer bracket of low-voltage circuit breaker, can install simply, locate reliable and advantages of small volume through assembly unit location instrument transformer.
The technical scheme that the present invention adopts is: be assemblied to form by three kinds of supports of first, second, third support, first, second at least two of support envelope that is U type structure is the 3rd support of " worker " type structure; Said first support is made up of with roof and the diapire that development length is identical in the same way along the sidewall two ends sidewall; Has a limited impression on the sidewall; A side opposite with bearing of trend on the roof has a positive stop lug boss; The roof outside is provided with one and cooperates boss, has on the diapire that corresponding cooperation boss matches on mating recesses and second support or the 3rd support; Roof and diapire that second support has sidewall and extends in the same way along the sidewall two ends; The roof outside have with first support on the mating recesses that cooperates boss to match; Have on the diapire cooperate boss respectively with first support 1 on mating recesses and the mating recesses on the 3rd support match, all the other structures of second support all are symmetrical set with first support; Roof and diapire that described the 3rd support has sidewall and extends to both sides along the sidewall two ends; On two big faces of sidewall inner chamber, have respectively and first support, the corresponding limited impression of second rack side wall, have a detent at any big face of two big faces of sidewall inner chamber and near the diapire position; Have mating recesses and the cooperation boss that cooperates boss, mating recesses to match with first support, the second support roof respectively at the two ends that roof extends; Have on the diapire with first, second support diapire on mating recesses, cooperation boss and the mating recesses that cooperates boss to match.
The invention has the beneficial effects as follows:
1, traditional electronic breaker three utmost points, four utmost points are that instrument transformer directly is installed on the base or adopts the three independent utmost points and four utmost point transducer brackets are realized assembling; Assemble numerous and diverse; Economic benefit is not high, and the assembled structure of transducer bracket can simply be realized the matching requirements of electronic breaker three utmost points, four utmost points like a cork.
2, the instrument transformer mounting means be any two stands from the instrument transformer side envelope instrument transformer; The slot to make way that the instrument transformer rivet of stepping down is arranged on the support; The limited impression on the dependence support and the appearance profile of instrument transformer can accurately be located; Than the top-down mounting means that is inserted in the base of traditional transducer bracket, it is more accurate to locate.
3, the cabling of traditional electronic breaker instrument transformer is numerous and diverse, chaotic, when assembling, is prone to caused certain potential safety hazard by other parts scratch and damage, and the lead-in wire cabling of fixing instrument transformer is orderly, and the location is reliable.
