Description
Technical field
The present invention relates to a kind ofly be used for master cock, the hydromechanical energy-storage module (Speichermodul) of the spring-type drive (Federspeicherantrieb) that is used for hydraulic pressure of the power switch (Leistungsschalter) of high pressure or medium voltage switchgear equipment especially with feature illustrated in claim 1.
Background technology
Be used for to handle the spring-type drive of hydraulic pressure of high-voltage circuit breaker for example from file DE 3408909 A1 and ABB publication Hydromechanical Spring Drive Type HMB-2, ABB Calor Emag Hochspannung GmbH is known and comprise in addition energy-storage module that be used for to handle high-voltage switch gear with the flexible member that works as energy accumulator among the Hanau-Gro auheim.Flexible member with in hydraulic block, guide, movable energy storage piston (Speicherkolben) concurs.Energy-storage module is arranged in for this reason in the situation of the other supply that does not have external enwergy that hydraulic unit driver to high-voltage circuit breaker provides pressure energy and (bestimmungsgem) operated drive and to this power switch according to the rules when Power supply disturbs or interrupt.
In the energy-storage module that is embodied as hydromechanical spring energy storage device (Federspeicher), the pressure that provides depends on the characteristic curve of employed spring or elasticity group.For the application of spring-type drive in power switch driver, constant pressure has larger meaning on the whole energy storage piston lift of energy storage piston, in order to guarantee the constant switching time of power switch.This at least approx can be easily only by disc spring (Tellerfeder) make realize.
For hydromechanical spring-type drive Worth Expecting is that the overcoming of energy storage piston that acts on loaded cylinder may constant or only change according to very little elastic constant, wherein this needed relatively high pretension.
This can be only in traditional helical spring or disc spring selection by the very little zone of spring characteristic curve realize so that the major part of the energy of storing can not be taken in the dropout situation.
Applied disc spring in being used for being applied in the known hydromechanical energy-storage module of power switch driver since its spring characteristic curve that successively decreases can be easily in the situation of enough pretensions provide almost constant pressure in the whole piston lift of energy storage piston.For the flat part of the needs of realizing spring characteristic curve, spring must be by pretension as far as possible.Therefore, on the one hand, the only sub-fraction that is stored in the energy in the spring is depleted.On the other hand, disc spring is compared quite expensive in for the size of using the energy-storage module necessity that acts on power switch driver with helical compression spring.Because the spring in the present employed energy-storage module is the major part of cost, so the significant cost of energy-storage module is impossible in the situation of the principle of work and power illustrated before the reservation.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of energy-storage module for hydromechanical spring-type drive, it is provided for being applied in the power switch driver, this energy-storage module avoided shortcoming above-mentioned and especially the utilization of the best by the storable energy that in energy-storage module, exists reduce the cost of spring-type drive.

According to the present invention, transmission module is embodied as rod gear and is arranged in like that as previously described between the bearing-surface of spring to this.
Rod gear is made of lever and lever accommodation section (Hebelaufnahme), wherein, the lever accommodation section with lever mutually between and be connected with on every side member.Rod gear preferably has four lever accommodation sections.Two lever accommodation sections are tied to the spring place indirectly, and the 4th lever accommodation section is connected with anchor plate (Ankerplatte) with the energy storage piston in the 3rd lever accommodation section, and anchor plate is connected with hydraulic cylinder or loaded cylinder again.In a preferred form of implementation according to energy-storage module of the present invention, because the large power that occurs is selected corresponding parallel structure with two of four levers identical transmission devices.Between the axle of lever accommodation section and lever, use sliding bearing and its to utilize in the axial direction snap ring to fix.
In a preferred design according to energy-storage module of the present invention, between supporting plate, preferably be furnished with six helical compression springs, it is held by supporting plate place, its end is corresponding.
Supporting plate is provided with at least one opening in a preferred form of implementation, it is used for upside-down motion (Bewegungsumkehr) as the opening for the keyset (Adapterplatte) that is positioned at the back.Keyset allows to utilize compression spring thus on the one hand with the lever accommodation section of transmission module and be connected with supporting plate via pull bar (Zuganker) on the other hand.
According to a further aspect in the invention, the energy-storage module according to the present invention that is used for spring-type drive is provided for master cock, especially high pressure or voltage power switch.
Utilization is according to energy-storage module of the present invention, when optimizing position relationship, the non-constant elastic force linearisation that is provided by helical compression spring is provided by means of employed rod gear and therefore in the situation of almost constant pressure, provides hydraulic energy on the whole piston lift at the energy storage piston by using helical compression spring in an advantageous manner, in order at this constant as far as possible power is applied on the energy storage piston of spring-type drive.
Obviously more favourable helical compression spring is compared in rod gear permission use in the situation of identical service performance of using in energy-storage module with disc spring.Transmission device can be regulated in addition like this, so that spring only needs less pretension, in order to clamp between supporting plate.Therefore, in the running of energy-storage module, almost can utilize the whole energy that are stored in the spring.
