Good horse good saddle matching energy-saving environmental protection and driving - energy-saving elevator dedicated feedback braking unit solution
Ningbo Shucheng and North Jiangsu Hospital use 30 sets of IPC-PF-HLF-C series elevator-specific feedback brake units, using a cabinet-type installation method and a voltage rating of 380, which makes it possible to import high-energy-consumption brand elevators. While greatly increasing the safety life, it has more energy-saving effects, which greatly reduces the energy costs of the later construction of the central building. Ningbo Book City: Ningbo Book City has a total construction area of ​​81,686 square meters and a total investment of 800 million yuan. It is made by transforming the original industrial heritage. It is based on the theme of “The City of Lijiang Riverside Study†and has built a group of unique style buildings. There are a total of 8 buildings, making it a building community full of strong historical and cultural charm of Hong Kong City. The Northern Jiangsu People’s Hospital covers an area of ​​80,000 square meters and has a building area of ​​more than 120,000 square meters. It has nearly 500 million yuan in fixed assets and was established in 1900. It is located in the historical and cultural city Yangzhou, which is the oldest place in Yangzhou, Jiangsu Province. The largest and most comprehensive hospital is also a medical, teaching and research center in the region. These two units use the IPC elevator dedicated feedback braking unit, which is not only green, but also energy-saving and power-saving. It is the match between a good horse and a good saddle, and energy saving and environmental protection go hand in hand. Elevator energy is a long way to go Energy conservation and environmental protection is a common task facing humanity. The energy issue has been mentioned to an unprecedented height. China is a big energy consumer and a country with very little energy. Without energy support, development is empty talk. At present, more than 98% of domestic elevators use electric energy emitted from the state of power generation through brake resistors to dissipate heat, which on the one hand causes energy waste and on the other hand pollutes the environment, causing electromagnetic interference (increasing motor iron loss, copper consumption, etc.). , Improve the temperature of the elevator room, reduce the motor insulation and service life (refer to the international IEC8 °C rules). The energy saving and emission reduction space is huge, and the energy saving of elevators is a long way! The elevator is a potential energy load. The direction of the load torque varies with the load of the car, because it is determined by the gravity difference between the car and the counterweight. It is a potential energy load condition that uses the elevator to operate. Energy-saving methods that convert kinetic energy into electricity and use it. At present, the energy consumed on the braking resistor accounts for 25%-35% of the total electricity consumption of the elevator, and the conversion efficiency of energy feedback is about 85%. Therefore, the energy-saving effect of the elevator energy feedback link is generally 15-40% of the between. This can also be proved by an example, such as a 1350kg, 2.5m / s, 20-storey / 20-station elevator without energy feedback device installed before the power consumption of 831KWH / week, after the device power consumption is 590KWH / week, saving 30% The effect is still very obvious. IPC elevator energy-saving principle IPC-PF series feedback brake unit is a high-performance feedback brake unit for elevators manufactured using Canadian technology. The product can regenerate the regenerative energy generated by the motor during the speed regulation process, eliminating the need for external braking resistors. This product is equipped with a reactor and a noise filter, which can be directly connected to the 220V / 380V power grid to ensure that the inverter can run normally in the maximum energy saving state. However, some elevator energy-saving products that appear in China appear to be in the face of 220V elevators. Do nothing or technical performance is not safe and stable. IPC series products are applicable to all elevator frequency converters and are used together with international famous brand elevator frequency converters such as Yaskawa, Mitsubishi, Emerson, Hitachi, and Fujitsu to avoid the high temperature conditions caused by the heating of the braking resistors and improve the stability of the elevator operation. Performance and quality. IPC elevator energy-saving product features Product specification Power supply: The grid voltage is three-phase 220V/380V (depending on the model).

Energy Overview The Canadian company's development center is based on the United States, and its product commercialization project is based in Canada. The mass production of products is distributed around the world. IPC products are characterized by specialization, and all products have four objectives: high performance, automation, specialization, and environmental protection, and strive to provide users with simplified automation products. IPC claims that the complex work is done by its own developers, leaving the simplified use to the user. IPC does not produce complex products that can only be used by experts, but the internals of the products are all world-class new technologies that incorporate a large amount of artificial intelligence and use the most complex calculations. IPC products do not pollute the environment, do not pollute the power grid, and always follow the laws of harmony between technology and nature.
