Description
Technical field
The utility model is related to asynchronous machine starter device technical fields, are related specifically to a kind of split type liquid resistance
Starter.
Background technology
In order to improve the startability of large and medium-sized wire wound asynchronous motor, popular way is using liquid resistance
Starter；It is the automatic electrodeless adjustment resistance value by sealing in liquid resistance in rotor circuit, makes it from large to small most
After be zero, realize motor decompression without impact Horizon srr promoter.
Common liquid resistance starter is the electrolyte conduct that formulated is sealed in the rotor loop of coiling electric motor
Resistance by adjusting the distance between the concentration of electrolyte and change two-plate, makes to seal in resistance in start-up course always
Meet mechanical characteristics of motor to sealing in the requirement of resistance value, so as to which motor be made to obtain maximum detent torque and minimum start electricity
Uniform raising speed, smooth starting, short circuit rotor loop after startup complete the startup of motor in the case of stream.
But current liquid resistance starter is general and switchgear is as integral structure, electrolyte needs the appearance sealed
Device is contained, and cannot accomplish to be fully sealed between container and the external world, needs to set the driving device of electrode plate and electrode plate,
The time, grown can be so that electrolyte occurs revealing and the situations such as volatilize, if the relatively of leakage also affect switchgear more in this way
Safety, generate short circuit and other accidents.
Therefore it needs to design a kind of new starter.
Invention content
Technical problem to be solved in the utility model is the defects of overcoming the prior art, provides a kind of simple in structure, tool
There is preferable being fully sealed property, prevent electrolyte from revealing and volatilizing, improve service life and the safety of starter, prevent from switching
The split type liquid resistance starter of short circuit accident occurs for cabinet.
To achieve these goals, the utility model uses following technical scheme：
Split type liquid resistance starter, which is characterized in that include switchgear and start cabinet, the two is separated and independently set
It puts, is provided with liquid resistance device wherein starting in cabinet, liquid resistance device is connected in rotor circuit；The liquid
Resistance device is included there are one the container being fully sealed, and container is cylindric, and the side of container is provided with one close to bottom position
A return duct, return duct penetrate through container top upwards around container top, form a return line；In the container
It is provided with positive-negative electrode plate and filled with electrolyte, wherein negative electrode plate is fixed on container bottom end, and positive electrode plate can in container
It is up and down；The dome top surface and bottom lower surface of the container are both provided with electromagnet, solenoid actuated positive electrode plate
It is moved in container.
In said program, independent magnet control mechanism is provided in the startup cabinet, and mounted on sealing
In box, the electromagnet at container both ends is connected by conducting wire, electromagnet is also full package enclosed construction.
In said program, the positive electrode plate is mounted on corrosion resistant metal plate, the size of metallic plate with just
Electrode plate is identical, and metallic plate is used to increase the magnetic attracting force of positive electrode plate.
The utility model is by adopting the above-described technical solution, have the advantages that：
The utility model is simple in structure, has preferable being fully sealed property, it is therefore prevented that electrolyte is revealed and volatilization, improves
The service life of starter and safety, it is therefore prevented that short circuit accident occurs for switchgear.
