The vacuum circuit breaker is characterized in that: a vacuum arc extinguish chamber, a conductive loop and a transmission mechanism are arranged inside the insulating shell; the vacuum arc extinguish chamber is connected with a push rod and the transmission mechanism, and the push rod is driven to move up and down by the transmission mechanism to switch the switching state of the vacuum circuit breaker; the upper end of the vacuum arc extinguish chamber is connected with an upper bus by a soft connection mode, and the lower end of the vacuum arc extinguish chamber is provided with a conductive board, and is connected with a lower bus through a conductive board; and the conductive loop is formed among the upper bus, the soft connection, the vacuum arc extinguish chamber, the conductive board and the lower bus by the connection of the conductive board and the lower bus. Compared with the conventional air breaker, by adopting the vacuum arc extinguish chamber instead of an original contact system, electrical spark generated in an on-off process of a switch, is closed in the vacuum arc extinguish chamber, and is completely isolated from the external environment, so that contact of the electrical spark and external air is insulated, and the possibility of explosion and burning is prevented.
Description
Technical field
The present invention relates to the low tension switch technical field, specifically is a kind of low pressure all-purpose vacuum circuit-breaker.
Background technology
Generally all be as control in the circuit and protection equipment at present with all-purpose air breaker in low pressure (380V) distribution line; 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.
Summary of the invention
Technical problem solved by the invention is to provide a kind of low pressure all-purpose vacuum circuit-breaker that no electric spark exposes in deciliter process.
The present invention for the technical scheme that the technical solution problem adopts is:
A kind of low pressure all-purpose 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: described insulation shell inside is provided with vacuum interrupter, galvanic circle and transmission mechanism, described vacuum interrupter is connected with transmission mechanism with push rod, drive push rod by drive mechanism and move up and down the on off state that transforms vacuum circuit-breaker, the upper end of described vacuum interrupter by soft connection mode and Up Highway UHW between connect, lower end at described vacuum interrupter is provided with conductive plate, by connecting between conductive plate and the Down Highway, at Up Highway UHW, flexible connection, vacuum interrupter, form the galvanic circle between conductive plate and the Down Highway.
Described galvanic circle is connected with outboard circuit with Down Highway by Up Highway UHW, and Up Highway UHW and Down Highway pass through bolted after passing insulation shell.
Described conductive plate also closely links together by bolt and insulation shell shell.
Described transmission mechanism is made 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 by hinges, the other end of driving rocker and insulated tension pole flexibly connect, the other end by insulated tension pole connects the divide-shut brake rocking arm again, and the other end of described divide-shut brake rocking arm connects push rod.
Outside described 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 described driving rocker also is provided with tripping spring by rotating shaft.
Compare with existing air circuit, because the present invention 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 block contacting of electric spark and outside air, guaranteed the possibility of not having blast and burning.
The present invention can realize 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 a structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of low pressure all-purpose vacuum circuit-breaker, comprise insulation shell 1, vacuum interrupter 7, galvanic circle, operating mechanism 15, transmission mechanism and intelligent controlling device (not being shown specifically among operating mechanism 15 and the intelligent controlling device figure), wherein vacuum interrupter 7, galvanic circle, transmission mechanism are installed in insulation shell 1 inside, and operating mechanism 15 and intelligent controlling device are installed in insulation shell 1 outside; The galvanic circle is connected with outboard circuit with Down Highway 8 by Up Highway UHW 6, Up Highway UHW 6 and Down Highway 8 pass insulation shell 1 by bolted, Down Highway 8 is connected with conductive plate 9 in insulation shell 1 bottom, conductive plate 9 is bolted to insulation shell 1 bottom, conductive plate 9 connects vacuum interrupter 7, current transformer 5 is equipped with in vacuum interrupter 7 upper ends, and vacuum interrupter 7 upper ends connect Up Highway UHW 6 by flexible connection 4; Transmission mechanism is by mechanism's rocking arm 16, driving rocker 14, divide-shut brake rocking arm 10, insulated tension pole 11 constitutes, mechanism's rocking arm 16, driving rocker 14, divide-shut brake rocking arm 10 is fixed on the insulation shell 1 by fixed rotating shaft, one end of mechanism's rocking arm 16 connects an end of driving rocker 14 by hinges, the other end of driving rocker 14 connects an end of insulated tension pole 11, the other end of insulated tension pole 11 connects an end of divide-shut brake rocking arm 10, the other end of divide-shut brake rocking arm 10 then connects push rod 2, be with touch spring 3 on the push rod 2, the fixed rotating shaft in the middle of the driving rocker 14 is provided with tripping spring 13.
Its operation principle is: actuating operating mechanism 15 (but but also manual operation of electric operating) puts its energy storage in place, presses switch knob again, mechanism's motion of promptly doing to close a floodgate, mechanism's rocking arm 16 certain angle that turns clockwise.Under mechanism's rocking arm 16 drove, driving rocker 14 also and then turned clockwise.Insulated tension pole 11 is promoted to go up the top by driving rocker 14, divide-shut brake rocking arm 10 is rotated counterclockwise, thereby allows divide-shut brake rocking arm 10 other ends press down pull bar 2 and touch spring 3, and contact contacts and finishes switch and close a floodgate in the vacuum interrupter 7.During sub-switching operation, press opening button, operating mechanism is triped, under touch spring 3, tripping spring 13 effects, divide-shut brake rocking arm 10 turns clockwise, and driving rocker 14 and mechanism's rocking arm 16 are rotated counterclockwise, and drive push rod 2 and move upward, and separately finish the switch separating brake thereby reach vacuum interrupter 7 interior contacts.
