Abstract
The utility model belongs to the high voltage electrical apparatus field, and provides a high voltage breaker with an explosion-proof warning device. The high voltage breaker comprises a breaker body and an external box body. A knuckle piece is hinged onto the box body. One end of the knuckle piece is hinged to a push rod. The push rod is arranged on the box body vertically. The other end of the knuckle piece is hinged to a guide rod. The other end of the guide rod is a free end. A warning board is hinged onto the box body. A spring is arranged at the hinge joint of the warning board and the box body. An adjusting rod is arranged between the warning board and the free end of the guide rod. The hole in the middle of the adjusting rod is hinged onto the box body. One end of the adjusting rod is equipped with a buckling structure which buckles the warning board. The other end of the adjusting rod is equipped with a structure which cooperates with the free end of the guide rod. When an exception happens in the box body, a lot of gases are generated, the warning board can be turned over to remind people of overhaul, and the high voltage breaker has an advantage of accident prevention.
Description
Technical field
The utility model belongs to High-Voltage Electrical Appliances field, specifically relates to outdoor vacuum circuit breaker.
Background technology
Circuit breaker comprises breaker body and outside casing, in the time of the alternate of circuit breaker case inside and insulation against ground electric discharge or vacuum interrupter unstable properties, in casing, can produce in a large number gas, air pressure inside raises fast, and in prior art, circuit breaker distribution box does not have other alarming device, the gas phenomenon of usually blasting that causes pressure to raise, when box of the circuit breaker explosion time, can damage other electrical equipment in box of the circuit breaker, cause damage.
Summary of the invention
the purpose of this utility model is exactly for above-mentioned shortcoming, provide a kind of when box of the circuit breaker internal gas is more, pressure can remind people to overhaul when larger, the generation of minimizing accident, protects the primary cut-out with explosion prevention warning device of other electrical equipment.
The technical scheme that the utility model adopts is: the primary cut-out with explosion prevention warning device, comprise breaker body and outside casing, it is characterized in that: a hinged knuckle part above described casing, the hinged push rod in knuckle part one end, above the vertical casing of push rod, arrange, the hinged guide rod of the knuckle part other end, the other end of guide rod is free end, also have a warning sign to be hinged on casing, warning sign and casing hinged place also have spring, between warning sign and the free end of guide rod, also has an adjusting rod, porose being hinged on casing in the middle of adjusting rod, adjusting rod one end has the buckle structure sticking below warning sign, the other end of adjusting rod has the free-ended structure of the guide rod of cooperation, in the time that guide rod stretches out, the free side pressure of guide rod adjusting rod, the buckle structure of the other end of adjusting rod sticks warning sign, in the time that guide rod is retracted, the free end of the guide rod adjusting rod that comes off, the other end buckle structure of the adjusting rod warning sign that comes off.
The beneficial effects of the utility model are: when occurring when abnormal, will to produce more gas in casing, warning sign will overturn, and reminds people's maintenance, has advantages of the generation of preventing accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1. casing 2. knuckle part 3. push rod 4. guide rods 5, warning sign 6, adjusting rod 7, buckle structure in figure.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, there is the primary cut-out of explosion prevention warning device, comprise breaker body and outside casing 1, it is characterized in that: a hinged knuckle part 2 above described casing, the hinged push rod 3 in knuckle part one end, push rod 3 is vertical to be arranged above casing, the hinged guide rod 4 of knuckle part 2 other ends, the other end of guide rod 4 is free ends, also have a warning sign 5 to be hinged on casing, warning sign and casing hinged place also have spring, between warning sign and the free end of guide rod, also has an adjusting rod 6, porose being hinged on casing in the middle of adjusting rod, adjusting rod one end has the buckle structure 7 sticking below warning sign, the other end of adjusting rod has the free-ended structure of the guide rod of cooperation, in the time that guide rod stretches out, the free side pressure of guide rod adjusting rod, the buckle structure of the other end card of adjusting rod sticks warning sign, in the time that guide rod is retracted, the free end of the guide rod adjusting rod that comes off, the other end buckle structure of the adjusting rod warning sign that comes off.
When abnormal in casing, will produce more gas, casing internal gas pressure raises, casing will dilatancy, and the casing of distortion acts on push rod, and push rod moves up, due to the articulated knuckle part of push rod, knuckle part will rotate, and knuckle part rotates and pulls guide rod to move, the guide rod adjusting rod that will come off, buckle structure 7 and the warning sign of adjusting rod come off, and warning sign will overturn under the effect of spring, and maintainer will find easily, maintenance, can fix a breakdown in time.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed in the scope of the claims of the present utility model.
