Description
Affiliated technical field
The utility model belongs to resistance soft start of motor liquid and speed adjusting technique field, relate to a kind of motor liquid resistance soft start speed governing and electrical load experimental rig battery lead plate, particularly a kind of high voltage, the soft start speed governing of high-power AC and DC motor liquid resistance and electrical load experimental rig battery lead plate of being applicable to.
Background technology
When motor carries out liquid resistance soft start speed governing and electrical load test, generally need in major loop, to seal in liquid resistance box and utilize the load of liquid resistance as soft start and speed regulating device, change in the liquid resistance box moving, the distance of fixed electrode plate can change the liquid resistance resistance that seals in the loop, reach the purpose of flexible starter for electric motor and speed governing, but motor is when carrying out liquid resistance soft start and speed governing operation, metal in the liquid resistance box is moving, the corrosion of fixed electrode plate is very serious, trace it to its cause: the one, battery lead plate is under the situation of bearing high voltage and big electric current, in a short period of time, moving, near the fixed electrode plate resistor fluid partial vaporization, Joule heat rises the anxious work of resistor fluid temperature, and high temperature produces the flash burn corrosion to metal electrode board; The 2nd, in order to improve the electric conductivity of resistor fluid, in resistor fluid, added the alkaline electrolyte component of doses, electrolyte substance produces the soda acid chemical corrosion to metal electrode board; The 3rd, resistor fluid is under the effect of AC and DC electricity (particularly direct current), and electrolyte substance is to the electrochemical corrosion of metal electrode board.Metal in the resistor fluid case is moving, the fixed electrode plate is under the acting in conjunction of the chemical corrosion of above-mentioned flash burn burn into soda acid, electrochemical corrosion, metal is moving, the fixed plate corrosion rate is fast, useful life is short, or cause the operating current of motor to change, resistance box load performance instability influences the normal operation of soft start speed governing of motor liquid resistance and electrical load experimental rig.For the corrosion of metal electrode board, traditional method is to adopt the copper material battery lead plate, and carries out the nickel plating preservative treatment.This metal copper material nickel coating electrode plate can be alleviated the soda acid chemical corrosion effectively, but is difficult to solve the problem of flash burn corrosion and electrochemical corrosion.Helplessly, can only be out of service, change battery lead plate, have a strong impact on the normal use of motor and relevant device.Therefore, for the ensuring equipment reliability of operation, just must select for use a kind of for the chemical corrosion of flash burn burn into soda acid, electrochemical corrosion have simultaneously good corrosion resistance can material, make soft start speed governing of motor liquid resistance and electrical load experimental rig battery lead plate with this, but the selection problem of kind electrode plate fails so far to solve.
Summary of the invention
The purpose of this utility model is exactly at the above-mentioned traditional motor liquid resistance soft start speed governing and the weak point of electrical load experimental rig usefulness metallic copper nickel coating electrode plate, and resistance of a kind of motor liquid and speed regulating device battery lead plate be provided, particularly a kind of be applicable to high voltage, high-power directly, the soft start speed governing of alternating current motor liquid resistance and electrical load experimental rig battery lead plate.
Technical solution of the present utility model is: a kind of motor liquid resistance soft start speed governing and electrical load experimental rig battery lead plate, comprise moving, fixed electrode plate, and it is characterized in that: battery lead plate adopts graphite sheet with material.
Graphite is a kind of nonmetal crystal material with carbon element, and the physics, the chemical property that have many excellences such as high temperature resistant, resistance to oxidation, anticorrosive, anti-thermal shock, good toughness, self-lubricating intensity height, electric conductivity be strong because of it are widely used.Technical solution of the present utility model is to utilize high temperature resistant, the resistance to oxidation of graphite, anticorrosive, characteristics such as electric conductivity is strong, replaces with graphite cake that traditional metallic copper nickel plating is moving, the fixed electrode plate.The electric conductivity of graphite material battery lead plate, mechanical shock-resistance performance can both satisfy the operation technique requirement of liquid resistance box, the burn into of anti-flash burn acid and alkali-resistance chemical corrosion of battery lead plate and the ability of electrochemical corrosion resistant have been improved simultaneously again, make it durable in use, needn't often change battery lead plate.And this technical scheme enforcement is very convenient, only need virgin metal copper nickel coating electrode plate is replaced with graphite material battery lead plate, and other structure and technology is constant.
The beneficial effects of the utility model are: soft start speed governing of the described motor liquid resistance of this technical scheme and electrical load experimental rig graphite material battery lead plate, at work flash burn burn into soda acid chemical corrosion of battery lead plate, the problem of electrochemical corrosion have been solved, strengthened the job stability of device, prolonged the useful life of device, reduce maintenance cost, saved maintenance time.Simultaneously much lower than the unit price of copper material because of the unit price of graphite, reduced the manufacturing cost of installing.
