Description
Technical field
The utility model relates to the low tension switch technical field, specifically is a kind of low-voltage vacuum circuit breaker.
Background technology
In low pressure (380V) distribution line, all be generally at present as control in the circuit and protection equipment with all-purpose air breaker; This circuit breaker is owing to its contact portion is all exposed; Therefore in deciliter process; The electric spark that contact produced all is exposed in the air, if contain fuel gas in the air, in case touch the danger of just might blasting of this electric spark.Therefore all can not use this air circuit in chemical enterprise, mine and some other enterprises that might produce fuel gas.In view of the situation, need the hermetic low tension switch of a kind of contact portion.
The utility model content
The technical problem that the utility model solved is to provide a kind of low-voltage vacuum circuit breaker that no electric spark exposes in deciliter process.
The utility model for the technical scheme that the technical solution problem adopts is:
A kind of low-voltage vacuum circuit breaker; Include insulation shell and the operating mechanism and the intelligent controlling device that are installed in the insulation shell outside; It is characterized in that: said insulation shell set inside vacuum interrupter, galvanic circle and transmission mechanism, said vacuum interrupter is connected with transmission mechanism with push rod, drives push rod through drive mechanism and moves up and down the on off state that transforms vacuum circuit-breaker; Connect between mode and the Up Highway UHW of the upper end of said vacuum interrupter through soft connection; Lower end at said vacuum interrupter is provided with conductive plate, through connecting between conductive plate and the Down Highway, between Up Highway UHW, flexible connection, vacuum interrupter, conductive plate and Down Highway, forms the galvanic circle.
Said galvanic circle is connected with outboard circuit with Down Highway through Up Highway UHW, and Up Highway UHW and Down Highway pass through bolted after passing insulation shell.
Said conductive plate also closely links together through bolt and insulation shell shell.
Said transmission mechanism is made up of mechanism's rocking arm, driving rocker, insulated tension pole and divide-shut brake rocking arm; The external operating mechanism of one end of mechanism's rocking arm; The other end connects an end of driving rocker through hinges; The other end of driving rocker and insulated tension pole flexibly connect, and the other end through insulated tension pole connects the divide-shut brake rocking arm again, and the other end of said divide-shut brake rocking arm connects push rod.
Outside said push rod, be with touch spring, be used to control the distance of the indoor contact pressure of vacuum extinction and transmission mechanism stretching and compression push rod.
The centre of said driving rocker also is provided with tripping spring through rotating shaft.
Compare with existing air circuit; Because the utility model utilizes vacuum interrupter to replace former contact system; It is indoor that the electric spark that switch is produced in deciliter process is enclosed in vacuum extinction; Isolated fully with the external world, therefore blocked contacting of electric spark and outside air, guaranteed the possibility of not having blast and burning.
The utility model can be realized exchanging with the DW45 circuit breaker also with reference to the outline overall and installing dimensions of DW45 intelligent universal air circuit, provides users with the convenient and saving economically.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
