Abstract
The utility model relates to a mining high-explosive switch and particularly provides a novel mining flame-proof two-combined high-explosive switch, which solves the problem in the prior art that existing mining high-explosive switches are inconvenient in underground transportation, installation, assembly and maintenance, poor in reliability and short in service life. The novel mining flame-proof two-combined high-explosive switch comprises a switch cavity. The switch cavity is composed of two main cavities, a control cavity, a wire incoming cavity and a wire outgoing cavity. The left outer cavity wall of one main cavity and the right outer cavity wall of the other main cavity are fixed together as a whole. A solid insulation type vacuum circuit breaker is arranged in each main cavity respectively. The operating mechanisms of the two solid insulation type vacuum circuit breakers are respectively in the form of a mono-stable permanent-magnet operating mechanism. The novel mining flame-proof two-combined high-explosive switch is applicable to underground conditions.
Description
Technical field
The utility model relates to mining high-explosive switch, specifically a kind of new type mining flame proof two combination high-explosive switchs.
Background technology
Mining high-explosive switch is widely used in having the down-hole of damp and coal dust, and it both can provide reliable control and protection for downhole neutral point isolated neutral system with for transformer substation system, also can be for line-start motor continually not.Existing mining high-explosive switch is because self structure is limit, the following problem of ubiquity: one, the volume of existing mining high-explosive switch is generally comparatively heavy, causes it to be not easy to underground transportation and installation.They are two years old, the operating mechanism of the circuit breaker of existing mining high-explosive switch generally adopts spring operating mechanism, because spring operating mechanism has that part is many, complex structure, many, the bulky shortcomings in fault point, cause on the one hand it to be not easy to assembling and maintenance, cause on the other hand its poor reliability and useful life short.Based on this, be necessary to invent a kind of brand-new mining high-explosive switch, the problems referred to above that exist to solve existing mining high-explosive switch.
Summary of the invention
The utility model is not easy to underground transportation and installation in order to solve existing mining high-explosive switch, be not easy to assembling and maintenance, poor reliability, useful life short problem, a kind of new type mining flame proof two combination high-explosive switchs are provided.
The utility model is to adopt following technical scheme to realize: a kind of new type mining flame proof two combination high-explosive switchs, comprise switch cavity; Described switch cavity comprises main cavity, controls cavity, inlet wire cavity, outlet cavity; The number of main cavity is two; The left outer chamber wall of one of them main cavity and the right outer chamber wall of another main cavity are fixed as one; A solid insulation formula vacuum circuit-breaker is respectively installed in two main cavities; The operating mechanism of two solid insulation formula vacuum circuit-breakers is monostable permanent-magnet operating mechanism; The number of controlling cavity is two; One of them left outer chamber wall and another right outer chamber wall of controlling cavity of controlling cavity is fixed as one, and two lower outer chamber wall of controlling cavity are fixed as one with the upper outer chamber wall of two main cavities respectively; The number of inlet wire cavity is one; The front outer chamber wall of inlet wire cavity and two rear outer chamber wall of controlling cavity are fixed as one; The number of outlet cavity is one; The front outer chamber wall of outlet cavity and the rear outer chamber wall of two main cavities are fixed as one, and the upper outer chamber wall of outlet cavity and the lower outer chamber wall of inlet wire cavity are fixed as one.
Specific works process is as follows: when monostable permanent-magnet operating mechanism not when electric, solid insulation formula vacuum circuit-breaker keeps "on" position.When switching on to monostable permanent-magnet operating mechanism, solid insulation formula vacuum circuit-breaker carries out separating brake action.Based on said process, compare with existing mining high-explosive switch, a kind of new type mining flame proof two combination high-explosive switch tools described in the utility model have the following advantages: one, a kind of new type mining flame proof two combination high-explosive switchs described in the utility model are by adopting main cavity, control cavity, inlet wire cavity, outlet cavity to be combined into switch cavity, make the volume of self lighter and handier, be very easy to thus underground transportation and installation.They are two years old, a kind of new type mining flame proof two combination high-explosive switchs described in the utility model no longer adopt spring operating mechanism, but adopt the solid insulation formula vacuum circuit-breaker with monostable permanent-magnet operating mechanism, it is by utilizing advantage and the little advantage of solid insulation formula vacuum circuit-breaker volume that monostable permanent-magnet operating mechanism part is few, simple in structure, fault point is few thus, be very easy on the one hand self assembling and maintenance, effectively strengthen on the other hand the reliability of self, and effectively extended the useful life of self.In sum, a kind of new type mining flame proof described in the utility model two combination high-explosive switchs are based on brand new, efficiently solve that existing mining high-explosive switch is not easy to underground transportation and installation, is not easy to assembling and maintenance, poor reliability, useful life short problem.
The utility model is simple in structure, reasonable in design, efficiently solve that existing mining high-explosive switch is not easy to underground transportation and installation, is not easy to assembling and maintenance, poor reliability, useful life short problem, be applicable to down-hole.
