Abstract
The utility model discloses a solid sealed pole contact finger type conductive movement mechanism applied to a high voltage switch. The mechanism comprises a solid sealed pole and an isolating pipe. A through hole is arranged on the solid sealed pole. The isolating pipe passes through the through hole. A number of grooves are arranged in the through hole. Spring contact fingers are arranged in the grooves. The mechanism provided by the utility model has the advantages of reasonable structure design, simple installation and replacement, reliable transmission, high conductivity performance and long service life.
Description
Technical field
The utility model relates to the technical field of high-voltage switch gear, particularly a kind of finger-contact type of the pole for high-voltage switch gear conduction motion.
Background technology
High voltage switchgear refer to voltage 3kV and more than, the indoor and outdoor AC switchgear moved in frequency 50Hz and following electric power system.Be mainly used in the electric power system control and protection of (comprising the users such as power plant, transformer station, electric line and industrial and mining enterprises); both can a part of power equipment or circuit need to be dropped into or out of service according to operation of power networks; also can when power equipment or line failure, faulty component be excised fast from electrical network, thereby guarantee the normal operation of fault-free part in electrical network and equipment, operating maintenance personnel's safety.Therefore, high voltage switchgear is very important equipment for power transmission and distribution, its safety, reliability service to electric power system safe, effectively move tool and be of great significance.In high voltage switchgear, particularly important with high-voltage switch gear again, the conduction motion structure of the pole on existing high-voltage switch gear is mainly the mode that adopts external device (ED) Mume flower contact interlock isolated tube, the shortcoming that this structure exists is installed loaded down with trivial details exactly, volume is large, electric conductivity is unstable, and anti-external environment condition grade is low etc.
The utility model content
The purpose of this utility model is that the shortcoming that overcomes prior art is with not enough, and a kind of finger-contact type of the pole for high-voltage switch gear conduction motion is provided.
The purpose of this utility model is achieved through the following technical solutions:
The utility model is for the conduction motion of the pole finger-contact type of high-voltage switch gear, comprise pole and isolated tube, on described pole, offer through hole, isolated tube is through this through hole, be provided with many grooves in described through hole, spring touch finger is installed in groove.
Preferably, described groove is groove shape, and spring touch finger just can be contained in groove.
Preferably, described groove is 2, is provided with 1 spring touch finger in every groove.
Preferably, described spring touch finger is the canted coil spring fingertip.
Preferably, described spring touch finger is by beryllium-bronze silk or the machine-shaping of cobalt ultramarine copper wire.
Preferably, described spring touch finger is to be positioned in the groove of pole the inside after compression.
The utility model has following advantage and effect with respect to prior art:
The utility model reasonable in design, installation is changed easy, reliable transmission, electric conductivity is high, long service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, the utility model is for the conduction motion of the pole finger-contact type of high-voltage switch gear, comprise pole 1 and isolated tube 2, on described pole 1, offer through hole, isolated tube is through this through hole, described through-hole surfaces is provided with many grooves 4, spring touch finger 3 is installed in groove, and work is, isolated tube 2 stretching motion in through hole, and be subject to spring touch finger 3 lock rings and extruding, realize the conducting of electric current.
Described groove is groove shape, and spring touch finger just is contained in groove; Be provided with spring touch finger in described groove; Described spring touch finger is by beryllium-bronze silk or the machine-shaping of cobalt ultramarine copper wire, certainly, also can select the metal of other material, in the present embodiment, described spring touch finger is in the groove by being positioned over the pole the inside after suitable compression, in the present embodiment, the quantity of groove is 2, be provided with 1 spring touch finger in every groove, in the utility model, described spring touch finger is chosen as the canted coil spring fingertip.
Above-described embodiment is preferably execution mode of the utility model; but execution mode of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection range of the present utility model.
