Three years maintenance-free! Fengchuang solid capacitor transformer prolongs the life of cold chain logistics equipment
Read Time:4 Minute, 2 Second
In the cold chain logistics industry, the stable operation of low-temperature storage and transportation equipment is directly related to the quality and safety of fresh food and pharmaceutical products. As the "power heart" of cold chain equipment, the reliability and maintenance cost of transformers have always been the pain point of the industry. Aiming at this demand, Shanghai Fengchuang Industrial Co., Ltd. innovatively introduced the solid-state capacitor transformer. With the core advantage of "three-year maintenance-free", it greatly reduced the frequency of downtime and maintenance of cold chain equipment, extended the service life of equipment, and provided an efficient and stable power solution for the cold chain logistics industry.
As a national high-tech enterprise deeply involved in the field of electrical equipment, Shanghai Fengchuang Industrial Co., Ltd. has always been guided by scene demand. The transformer products of its "Fengyun-Fonyun" brand have accumulated mature technical experience in the fields of industry and new energy. It is found that the traditional cold-chain transformer uses liquid electrolytic capacitors, and the electrolyte is volatile and the aging of the capacitors is accelerated in the environment of frequent temperature fluctuations from-30℃ to 50℃, so it needs to be shut down for maintenance every 6-12 months on average, and the equipment shutdown caused by each maintenance will cause tens of thousands of losses. At the same time, capacitor failure may also lead to transformer failure, resulting in power failure of cold chain system and deterioration of goods.
The core breakthrough of Fengchuang solid-state capacitor transformer is to replace the traditional liquid electrolytic capacitor with solid-state polymer capacitor. This kind of capacitor takes polymer as electrolyte, which has the characteristics of high temperature resistance, low temperature resistance and no liquid leakage. It can work stably in a wide temperature environment from-40℃ to 105℃, and its life is more than 5 times that of traditional electrolytic capacitors. The accelerated aging test shows that its service life can reach 10 years under typical working conditions of cold chain equipment, far exceeding the industry average level, and fundamentally realizing the promise of "three-year maintenance-free".
In the circuit design, the transformer integrates an "intelligent capacitor state monitoring system", which collects the parameters of the capacitor such as temperature, voltage and impedance in real time through the built-in sensor, and judges the healthy state of the capacitor after chip analysis. When an abnormality is detected, the system will send an early warning signal to the cold chain monitoring platform through RS485 interface, which is convenient for operation and maintenance personnel to intervene in advance and avoid sudden failure. In addition, the transformer adopts the "three-proof sealing structure", and the protection level of the shell reaches IP65, which can resist the common condensed water and dust erosion in the cold chain environment and further reduce the maintenance requirements.
Aiming at the special power demand of cold chain equipment, Fengchuang optimized the load adaptability of transformer. Its output voltage regulation rate is controlled within 1%, which can keep stable power supply even under the impact load when the compressor is started, and reduce the influence of voltage fluctuation on temperature control accuracy. At the same time, the no-load loss of the transformer is reduced by 30%, and the operation efficiency is improved to over 96%, which can help a single cold chain equipment save about 1200 yuan in electricity fee every year.
The practical application data show that after the replacement of Fengchuang solid capacitor transformer in a pharmaceutical cold chain storage center, the frequency of equipment maintenance has been reduced from 2 times a year to 0 times, and the downtime has been reduced by 180 hours in three years, so as to avoid the deterioration loss of drugs caused by power failure exceeding 500,000 yuan. The director of operation and maintenance of the center said: "The maintenance-free feature makes it unnecessary for us to make a shutdown plan for transformer maintenance. With the intelligent early warning function, the reliability of the equipment has been improved by 80%, which greatly reduces the operational risk."
At present, Fengchuang solid-state capacitor transformer has passed ISO13485 medical device quality management system certification, which is suitable for various scenarios such as medical cold storage, fresh refrigerated trucks and cold chain containers. In the future, Fengchuang will further optimize the energy density of solid-state capacitors, and plans to launch an integrated transformer with integrated energy storage function to help the cold chain logistics upgrade to the direction of "low maintenance, high reliability and energy saving" and provide a solid power guarantee for the high-quality development of the cold chain industry.
