Abstract
The utility model discloses a fixation-encapsulation terminal post for a vacuum circuit breaker. The fixation-encapsulation terminal post comprises a fixation-encapsulation body, an arc extinguish chamber, a heat abstractor and an electric conduction device, wherein a plurality of cavities are formed in the fixation-encapsulation body; the arc extinguish chamber is arranged in the fixation-encapsulation body; the heat abstractor is arranged at one end of the arc extinguish chamber; and the electric conduction device is arranged at the other end of the arc extinguish chamber. According to the fixation-encapsulation terminal post for the vacuum circuit breaker, the same arc extinguish chamber can be used for different rated voltages, the arc extinguish chamber does not need an additional fastener, and a current carrying piece is firmly and fixedly arranged at the right position by casting resin at the periphery of the current carrying piece, so that the number of the parts of the arc extinguish chamber is reduced greatly, the maintenance is simple and convenient, and the service life is long. A ceramic piece of the arc extinguish chamber is short in length and small in diameter so as to be beneficial to miniaturization. According to the fixation-encapsulation terminal post, the solid insulation of a switch cabinet is facilitated, and the size of the cabinet body is reduced greatly.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker equipment, especially relates to a kind of solid sealed pole of vacuum circuit breaker.
Background technology
Along with the continuous development of national economy, electric network composition and part throttle characteristics are complicated day by day, for protection equipment and personal safety, the requirement of Supply Security, reliability are had higher requirement.
Modal circuit safety device is a circuit breaker, and it is a kind of existing hand switch effect, can carry out decompression, under-voltage, overload and the electrical equipment of short-circuit protection again automatically.It can be used to distribute electric energy; Do not start asynchronous motor continually; Power circuit and motor etc. are carried out protection, can automatic shutdown circuit when serious overload or short circuit and fault such as under-voltage take place for their, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And behind the disjunction fault current, generally need not change parts, obtained to use widely.
And the pole of present vacuum circuit-breaker can not be used for the voltage of multiple amount, and insulation property are not good, and number of parts is more simultaneously, is not easy to safeguard.
The utility model content
The purpose of the utility model is to provide a kind of different rated voltages that are used for, and maintenance is easier, the solid sealed pole of vacuum circuit breaker that the life-span is longer.
For solving the problems of the technologies described above, the utility model solid sealed pole of vacuum circuit breaker comprises: admittedly seal body, form a plurality of chambers in the body said the envelope admittedly; Arc control device, said arc control device are arranged on and saidly seal in the body admittedly; Heat abstractor, said heat abstractor are arranged on an end of said arc control device; Electric installation, said electric installation is arranged on the other end of said arc control device.
Said electric installation comprises: the conduction slide mass, and an end of said conduction slide mass is connected with said arc control device; Conducting ring, said conducting ring are arranged on the both sides of said conduction slide mass inwall.The other end at said electric installation also further is provided with insulated tension pole, and said insulated tension pole is connected with said electric installation through packing ring.Said heat abstractor is a fin.Two ends at said arc control device also further comprise upper and lower outlet.Be enclosed with epoxy resin in the said outside of sealing body admittedly.
The utility model solid sealed pole of vacuum circuit breaker can make same arc control device can be used for different rated voltages; The securing member that arc control device need not add; Current-carrying spare is fixed on its position by casting resin on every side securely; This has just significantly reduced the part count of arc control device, and maintenance is easier, and the life-span is longer.The ceramic member length of arc control device own is shorter and diameter is littler, helps miniaturization.Pole also helps realizes the solid insulation switch cabinet, and cabinet is greatly reduced.

Embodiment
Below in conjunction with accompanying drawing the utility model the utility model solid sealed pole of vacuum circuit breaker is done further explain.
As shown in Figure 1, the utility model solid sealed pole of vacuum circuit breaker comprises: admittedly seal body 1, in sealing body 1 admittedly, form a plurality of chambers, be enclosed with epoxy resin in the outside of sealing body 1 admittedly; Arc control device 4, arc control device 4 are arranged in the solid envelope body 1; Be arranged on the fin 5 of an end of arc control device 4; Electric installation, electric installation are arranged on the other end of arc control device 4.
Electric installation comprises: conduction slide mass 7, and an end of conduction slide mass 7 is connected with arc control device 4; Conducting ring 3, conducting ring 3 are arranged on the both sides of conduction slide mass 7 inwalls.The other end at electric installation also further is provided with insulated tension pole 2, and insulated tension pole 2 is connected with electric installation through packing ring.Also further comprise outlet 6 and following outlet 8 at the two ends of arc control device 4.
The utility model solid sealed pole of vacuum circuit breaker can make same arc control device can be used for different rated voltages; The securing member that arc control device need not add; Current-carrying spare is fixed on its position by casting resin on every side securely; This has just significantly reduced the part count of arc control device, and maintenance is easier, and the life-span is longer.The ceramic member length of arc control device own is shorter and diameter is littler, helps miniaturization.Pole also helps realizes the solid insulation switch cabinet, and cabinet is greatly reduced.
The preferred embodiment of below the utility model having been created specifies; But the utility model is not limited to said embodiment; Those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, modification that these are equal to or replacement all are included in the application's the scope.
