Medical gas supply system _ Hebei Ericsson (certified) _ medical gas system, provided by Ericsson Hebei Medical Engineering Limited. Ericsson Hebei Medical Engineering Co., Ltd. (www.hslixin.com) is specialized in the "medical center specializing in the production of oxygen, radiation protection system, the hospital sewage treatment system, central aspiration" of the enterprise, the company of "honesty, hard service" concept provide you with the highest quality products and services. Welcome to inquire! Contact: Li Hongli. Medical Center oxygen supply system from the central station of oxygen, pressure relief devices, piping, valves and other components of oxygen quickly socket terminals. Central oxygen station is at the heart of the medical center oxygen system, the oxygen inside the station and piped to a rapid decompression device socket terminal at each ward each ward, and then through the humidifier after oxygen for the patient, it is safe to use, fast convenient, is a modern medical equipment in recent years, the rapid development. Leakage protection, referred to as leakage switch, also known as earth leakage circuit breaker is mainly used in the event of equipment failure and leakage of personal danger of fatal electric shock protection, overload and short circuit protection, can be used to protect the line or motor overload and Short circuit medical gas systems, also under normal circumstances as infrequent line conversion starts purposes. The main action performance parameters are: rated residual operating current, rated residual operating time, the rated residual non-operating current. Other parameters include: power frequency, rated voltage, rated current. ① rated leakage current under specified conditions, so that leakage protection action current value. For example 30mA protector, when the current value reached through 30mA, disconnect the power protection that action. ② rated residual operating time is the rated residual operating current is applied suddenly starting to protection circuit is cut off until the time. For example 30mA × 0.1s of protection, starting from the current value reaches 30mA medical gas supply system, the time to separate the main contacts ending not more than 0.1s. ③ rated residual non-operating current under specified conditions, the leakage protection action is not the current value, the general should be selected half action leakage current value. Such as leakage current of 30mA leakage protection, when the current value reaches below 15mA, the protector shall not operate, or because of the sensitivity of the action too easily mistaken for medical gas system, affecting the normal operation of electrical equipment. ④ other parameters such as: power frequency, rated voltage, rated current, etc., in the selection of leakage protection, should the lines and electrical equipment used to adapt. Leakage protection to adapt to the normal operating voltage of the grid rated voltage fluctuation range, if fluctuations will affect the protection work, especially electronic products medical gas system design, power supply voltage is lower than would be refused action protector rated working voltage. Leakage protection device rated current, and also consistent with the actual current in the loop, if the actual operating current is greater than the protection of the rated current, causing an overload and the protector malfunction.
