Technical field
The utility model relates to a kind of electricity supply and use technology field mesolow electric reactive compensating device.
Background technology
The low voltage power capacitor of prior art is several capacitor elements to be concentrated put into a housing the inside after in parallel or series connection, and its heat dispersion is poor, and the emphasis problem that capacitor will solve is dispelled the heat exactly.Capacitor self temperature of a normal operation is higher than 15-18 ℃ of ambient temperature ≈, when ambient temperature during at 50 ℃, the capacitor temperature rise may be up to arriving 68-70 ℃, along with the soaring element internal self-healing point of temperature constantly increases, cause the early stage fading loss of condenser capacity angle tangent value tg δ to increase simultaneously and ineffective.And the pad discharge resistance of prior art is all concentrated and is placed enclosure interior, thereby the sharp increase of heat when having accelerated the product operation.
Summary of the invention
The utility model mainly is that the power capacitor heat dispersion of solution prior art is poor, causes the early stage fading loss of condenser capacity angle tangent value tg δ to increase, thereby deficiency that may be ineffective; Thereby develop a kind of low voltage power capacitor that makes product self-radiating functional promotion to the limit.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of low voltage power capacitor, has capacitor element, the pad discharge resistance that connects capacitor element, explosion-proof safeties, the ladle body of capacitor element is installed, it is characterized in that: described ladle body is a discrete, and each ladle body holds a capacitor element, and three ladle bodies are set up in parallel; Be provided with upper cover above the described ladle body, ladle body is gone to the bottom and is provided with the footing plate, and described upper cover and footing plate are connected to the upper and lower of three ladle bodies, makes three ladle bodies connect into integral body; The big electric current pad of described connection capacitor element is arranged on the ladle body outside and converges, and discharge resistance is arranged at the ladle body outside.
The technical solution of the utility model can also be further perfect,
As preferably,
Described ladle body is that circular cylindrical cavity or square hollow cylinder are the most suitable.
Adopt the upright explosion-proof safeties of mariages formula that draw for circular shell; Adopt the explosion-proof safeties of horizontal drawing one chip for square casing.
There is an aperture at the about from top to bottom 30MM of described ladle body place, as filling balance.
Therefore, the beneficial effects of the utility model are: adopt separated structure owing to hold the ladle body of capacitor, unit one is divided into three, the radiating effect when having improved electric operation, when ambient temperature during at+50 ℃ capacitor self temperature remain on+55 ℃～60 ℃ between; The pad of wiring and discharge resistance are arranged at the ladle body outside between the capacitor element, reduce inner pyrotoxin when operation to greatest extent, guarantee inner fault-free hidden danger, guaranteed the condenser loss angle tangent value again under the power frequency rated voltage, 20 ℃ of tg δ≤0.1% simultaneously; Aspect explosion-proof safeties, adopt the horizontal drawing one chip for square casing, the safety plate that needed 200N just can draw back originally is advanced to only to be needed to get final product with the pulling force of 75N; Adopt the upright mariages formula of drawing for circular shell, the fuse that just can draw back the strength that needed 180N originally only is improved to and need gets final product with the 70N pulling force, electrical property safety factor when having improved the capacitor operation.By above improvement, improved product quality to greatest extent, prolong service life.
