Net source JYDT super capacitor energy conservation systems-elevator with frequency conversion traction equipment energy saving system is suzhou SAN yuan electric appliance Co., LTD. To meet customer needs and elaborate design of high performance elevator energy-saving equipment. Who can type load for such as: the elevator, oil pumping unit, hoist fast brake should the equipment, motor is inevitably exists renewable power generation process, the original deal with this part of the redundant energy method is: 1, increase the brake unit and braking resistance this part of electricity consumption in resistance, into heat wasted 2, the energy feedback device will power feedback to power grid, but the way has certain harmonic interference, and users can't enjoy saving electricity directly benefits. This energy-saving system change the original processing methods, green environmental protection energy storage device-super capacitors will originally in heat resistance of the consumption of energy storage up, when the equipment load operation feedback to dc bus frequency converter, priority for equipment use. So as to achieve the green, environmental protection, the purpose of saving energy.

Product project background

At present the consumption of electricity a year elevator about more than 450 Kwh. The elevator at run time down the re-load, light load up and slow down can produce the potential energy and braking energy, based on the power output to the frequency converter way dc bus, increased bus voltage. The frequency converter IGBT module has the compression restrictions, high voltage will damage the power module, causing damage to frequency converter.

Now technology to solve the problem of the main scheme has two kinds:

The first through the braking resistance and discharge. The scheme of simple structure, convenient installation, low cost. The energy through the braking resistance into heat form consume, but through the resistance off's energy will produce a lot of heat and an increase in room temperature, go against the normal operation of the elevator, often need to configure air conditioning cooling purposes, and also causes a lot of energy is wasted.

The second power feedback inverter technology. Elevator adopts energy feedback element, is on the high frequency inverter with dc bus voltage through the IGBT module into three-phase ac inverter to return to to power grid, will be in power effectively the status of the motor of the energy generated by the recovery, but there are also some disadvantages, such as the existence of more harmonic, work on the power grid has certain pollution, this scheme can save some of energy, but from the user's point of view because of the uneven feedback power, both neither can be the same structures within the other power facilities and exhausted, and should not be deducted from the electric meter of power consumption to reduce electricity use cost of users. In many cases the user meter installed energy feedback feedback unit electric meter reading after the but increases, so difficult user acceptance.

The third battery energy storage, this plan can store and release energy, but because the battery number, efficiency and put on the environmental impact, the program USES to have certain restriction.
