Abstract
The utility model relates to an auxiliary device which matches with a motor, and especially relates to an efficient energy-saving three-phase asynchronous motor compensator. The efficient energy-saving three-phase asynchronous motor compensator includes a housing, leads, capacitors, and a filler. The inside of the housing is provided with three capacitors, and the two ends of the capacitor are connected with the leads. The filler is filled in the housing and is poured into one body with the capacitors. The filler is the epoxy resin material. The parameter of the epoxy resin material matches with the optimal reactive compensation demand of an efficient energy-saving three-phase asynchronous motor, so the motor can be reactively compensated, and the power factor of the motor can be kept on an optimal idealized level in the whole process from the full load to the light load under the condition that the reactive compensation capacity has no change, and at the same time, the starting torque is increased. Besides, the self-excitation of the asynchronous motor after the motor is separated from an electrical network is avoided, so the motor performance is optimized, and the running efficiency is enhanced. The efficient energy-saving three-phase asynchronous motor compensator is safe, reliable, shock-proof, and leakage-proof, and has a small volume, a simple structure, and a long service lifetime, and can resist the low temperature of minus 40 DEG C. Besides, the connection and maintenance are convenient.
Description
Technical field
The utility model relates to a kind of and the supporting servicing unit of motor, particularly a kind of high efficiency energy-conserving threephase asynchronous compensator.
Background technology
In the power distribution network of each industrial and mining enterprises that widely applies threephase asynchronous, for satisfying the desired power factor specification of power supply department, generally all be to go into end at power distribution network to carry out reactive power compensation, reduce distribution loss.Energy-saving three-phase asynchronous motor is extensive use; Because motor disperses to be installed on each mechanized equipment, its corresponding by switchgear house in the formed transmission and distribution networks of each motor distribution, exist a large amount of reactive currents; Cause corresponding loss; And depend on the operating condition that threephase asynchronous is actual, the power factor of end of incoming cables also changes thereupon, far can not satisfy the demand of desirable reactive power compensation.
Summary of the invention
The goal of the invention of the utility model patent has provided novel compensator a kind of and high efficiency energy-conserving threephase asynchronous coupling; Its electromagnetic parameter nominal value comes from supporting high efficiency energy-conserving threephase asynchronous special electromagnetic design; And the structural design to be integrated with motor is directly installed on the motor; Thereby realize best reactive power compensation effect, and can stable operation under the low temperature of subzero-40 degree.
The technical scheme of the utility model: high efficiency energy-conserving threephase asynchronous compensator is characterized in that: its structure comprises housing, lead-in wire, capacitor, filler, in enclosure interior three group capacitors is housed, and two ends are connected to lead-in wire respectively; Filler is full of enclosure interior and is cast into one with electric capacity, and filler is an epoxide resin material.
The advantage of the utility model: the best reactive power compensation demand of the parameter of high efficiency energy-conserving threephase asynchronous compensator and high efficiency energy-conserving threephase asynchronous is complementary; Be able to reactive power compensation with motor self; Make it under the situation that does not change reactive compensation capacity; By fully loaded in service to the overall process of underloading, its power factor can both keep best idealized level, has also increased starting torque simultaneously effectively; In addition, can also avoid self-excitation after asynchronous motor and electrical network cut-off etc., further optimize motor performance, improve operational efficiency.Its volume is little, safe and reliable, simple in structure, wiring, easy to maintenance, low temperature resistant-40 ℃, shatter-proof, no leakage, long service life.
