Description
Technical field
The utility model relates to a kind of automatic water-replenishing device that is used for high voltage liquid resistor, belongs to liquid resistance and regulates automatically and the technical field of controlling.
Background technology
The liquid resistance device is and the matching used emphasis electric equipment of big-and-middle-sized alternating current motor, also is a kind of load regulation control resistance.Main component in its electrohydraulic box is an electrolyte, the long-time big current affects of using electrolyte to be subjected to ambient temperature and to produce of past as consume energy load or motor starting, electrolyte in the electrohydraulic box is heated and can volatilizees, need suitable keeping the skin wet, avoid the concentration of the electrolyte solution in the resistor fluid to change, influence the performance of the stable and motor starting of resistance, for this reason, it is the liquid resistance box supplementing water manually regularly that the user needs, and has so not only wasted time and energy but also troublesome maintenance.Therefore in order to address this problem, the applicant had once proposed " a kind of automatic watering apparatus that be used for liquid resistor " of application number for " 200720076435X " on November 6th, 2007, and attempt solves the problems referred to above that liquid resistance exists.But for different practical clients, under specific industrial and mineral condition to adding variantization of water function demand automatically, and just become an emphasis in the problem of introducing after automation adds wetting system safe in utilization.Such as: taking the high pressure power down mode to force the moisturizing scheme, the water pipe that enters after moisturizing is finished in the cabinet does not stay water, force to discharge, avoiding seepage or other contingencies to cause that the creepage of equipment or reduction insulation effect etc. cause problems such as unsafe factor, still is the problem that must consider when being worthy to be popularized this technical scheme.
The utility model content
The purpose of this utility model: being intended to provides a kind of automatic water-replenishing device that is used for high voltage liquid resistor at the problems referred to above.Wish both to have solved the automatic water supplement problem of high voltage liquid resistor device, the fail safe in the time of improving it simultaneously again and use, thereby stability and device security when improving whole high-tension resistive and using.
This automatic water-replenishing device that is used for high voltage liquid resistor, resistor fluid by splendid attire, settling the liquid reserve tank and the fluid infusion system of fixed plate and movable plate electrode to form, it is characterized in that: described fluid infusion system comprises external cistern, force (forcing) pump, choke valve, electromagnetically operated valve, waterline, and described cistern is formed the fluid infusion inlet pipeline by the force (forcing) pump, electromagnetically operated valve, the branch control valve that connect in regular turn on the waterline and the distributive pipe of being located on the branch control valve output port; Simultaneously not only control between the valve return duct on the pipeline and eduction valve but also be communicated with external cistern with dividing through being located at electromagnetically operated valve.
Described waterline is divided into two classes, and the pipeline that is led between the branch control valve by external cistern is the water delivery house steward, and its caliber is at 13 ~ 20mm; By minute control valve to the waterline of liquid reserve tank is distributive pipe, and its caliber is less than 12mm.
Described electromagnetically operated valve is a DC electromagnetic valve.
Automatic watering apparatus according to this liquid resistor of above technical scheme design, by the cistern of peripheral hardware and a whole set of controlled water delivery, the water recovery apparatus that connects to form with cistern, and to utilize the configuration in waterline aperture be that the automatic water supplement system can turn round under the condition of position safety more more.When liquid level drops to certain position, provide liquid phase automatically and add liquid.Promptly reduce the difficulty on safeguarding, can guarantee that the resistor fluid in the liquid reserve tank is in normal physicochemical property all the time simultaneously again; The final safe and reliable operation of realizing entire equipment.

Embodiment
The automatic watering apparatus of this liquid resistor as shown in the figure, it is a kind of improvement to existing liquid resistor, this automatic water-replenishing device that is used for high voltage liquid resistor, resistor fluid by splendid attire, settling the liquid reserve tank 13 and the fluid infusion system of fixed plate 6 and movable plate electrode 9 to form, it is characterized in that: described fluid infusion system comprises external cistern 1, force (forcing) pump 2, choke valve 3, electromagnetically operated valve 4, waterline, described external cistern 1 is by the force (forcing) pump 2 that connects in regular turn on the waterline, choke valve 3, electromagnetically operated valve 4, the distributive pipe 15 that divides control valve 8 and be located on branch control valve 8 output ports is formed the fluid infusion inlet pipeline; Simultaneously not only control between the valve 8 return duct 16 on the pipeline and eduction valve 17 but also be communicated with external cistern 1 with dividing through being located at electromagnetically operated valve 4.
Described waterline is divided into two classes, and the pipeline that is led between the branch control valve 8 by external cistern 1 is water delivery house steward 5, and its caliber is at 13 ~ 20mm; By minute control valve 8 to the waterline of liquid reserve tank 13 is distributive pipe 15, and its caliber is less than 12mm.
Described electromagnetically operated valve 4 is a DC electromagnetic valve.
When this technology of practice, the water system of mentioning in the technical scheme can be considered from the modular combination mentality of designing, under the prerequisite of the body design that does not change applying high voltage liquid soft starter product, carry out cell design in assembled component application mode, formulate the conventional products perforate, fixing technical matters combination requires and the electrical equipment programmatic interface guarantees the job security of system.
In addition, selecting when dividing the aperture of the hydraulic pipeline that cooperates of control valve branch mailbox branch road caliber≤12mm, main pipe rail≤20mm for use.Because the general rate of water make-up of soft start product is not required that not quite, quick benefit is intact yet, practicality is stronger.Discharge is little, away from the Level Detection mouth, also helps reducing level fluctuation, and moisturizing is a little slower can also close that moisturizing is unexpected malfunctioningly to cause moisturizing to win the more processing time for influencing a safe important node----! And caliber is littler, seems small and exquisite, and is also low to the assembly parts requirement, needs the negative effect of moisturizing little to high die pressing product.
