Background technique
Breaker is the electric current referred to close, carry and cut-off under normal loop condition and can close, when defined
Interior carrying and the switching device for cut-offfing the electric current under abnormal loop condition.Breaker is divided into high-voltage circuitbreaker by its use scope
With low-voltage circuit breaker, high-low pressure identification of boundaries is relatively fuzzyyer, and 3kV or more is generally known as High-Voltage Electrical Appliances.
Breaker can be used to distribute electric energy, infrequently start asynchronous motor, carry out power circuit and motor etc.
Protection, when serious overload or short circuit and the failures such as under-voltage occurs in they can automatic shutdown circuit, function is equivalent to molten
Disconnected combination device formula switch and cross underheat relay etc..And change components are not needed generally after disjunction fault current.Mesh
Before, it has had been widely used.
With the development and progress of society, the fast development of power industry is huge to the consumption of breaker, and breaker also exists
Huge numbers of families are more widely come into, use connecting rod for transmission mechanism inside high-pressure vacuum breaker at present, static contact and dynamic touching
Gap between head can constantly increase with continuing on, so that power can not be transmitted on drive mechanism well, into
It is unable to that breaker is allowed to realize effective divide-shut brake work, reduces the practicability of breaker.
Utility model content
The utility model aim is to provide a kind of high-pressure vacuum breaker, solves contact in background technique and is easy to appear jump
Dynamic problem provides a kind of high-pressure vacuum breaker that stability is good.
In order to achieve the goal above, the technical solution adopted in the utility model are as follows: a kind of high-pressure vacuum breaker, including shell
Body, the housing exterior walls side are connected with reset button and the switch knob below the reset button, the shell
Top side is fixedly connected with the connecting terminal of rectangular array, and the housing bottom is provided with hand compatible with the shell
Handle, the handle base are connected with run-on tab, and active wheel disc, the active wheel disc top are provided at the enclosure interior center
Pass through conveyer belt with bottom and be connected separately with the first driven wheel disc and the second driven wheel disc, leads at the top of the second driven wheel disc
It crosses insulated pull rod to be fixedly connected, the moving contact positioned at the enclosure interior is connected with by wire outlet seat at the top of the insulated pull rod,
It is placed in insulating cylinder outside the moving contact, the bracket of equidistant arrangement is provided between the insulating cylinder and the inner walls,
Conduit is connected at the top of the moving contact on the bracket, the insulating cylinder is run through at the top of the conduit and is extended to described
Outside insulating cylinder, it is connected with static contact compatible with the moving contact at the top of the conduit, described static contact one end is connected with
Static conductive rod, static conductive rod top two sides pass through transmission shaft and are connected with the transmission positioned at first driven wheel pan bottom
Gear.
Having the technical effect that for the utility model is referred to by the switch knob that switch knob connection is arranged on-board the circuit breaker
Show, under the action of reset button, breaker can be restored to open a way again, since circuit breaker internal uses the first driven wheel disc
With the two-way cooperation of the second driven wheel disc, power can effectively be passed through to conveyer belt and be transmitted in insulated pull rod, so that dynamic touching
The static contact that conduit connects on head, to realize wired divide-shut brake work, will not be moved with its gap of the increase of time is used
Contact and static conductive rod are arranged in insulating cylinder, can increase the insulation effect of breaker, can such breaker significantly
Stability is increased, design rationally, is effectively guaranteed the breaking-closing operating of breaker, extends service life.
