Embodiment Construction

[0031] The insulation monitor in the existing medical isolation power supply system is used to monitor the electrical parameters such as the insulation resistance, load current, and temperature of the medical isolation transformer secondary output of the medical isolation transformer, and send the monitored parameters to the remote terminal , and then displayed to the user, and the user analyzes and judges the data, and then determines the monitoring result. Since the existing insulation monitors only have monitoring functions, they cannot perform corresponding on-the-spot alarms with intuitive characteristics. As a result, in some application scenarios, the user's response speed to the faults related to the medical isolated power system is slow, and the faults cannot be detected in time. eliminate. In order to solve the above technical problems, an embodiment of the present invention provides an insulation monitor and a medical isolated power supply system.

Abstract

The invention discloses an insulation monitor and a medical isolation power supply system. the insulation monitor comprises a processing module, a displaying module and a data acquiring module, wherein the data acquiring module is used for acquiring specific electrical parameters and sending the acquired specific electrical parameters to the processing module; and the processing module is used for judging whether various electrical parameters meet the corresponding electrical failure conditions, and carrying out corresponding electrical alarm display through driving the displaying module when at least one electrical parameter meets the corresponding electrical failure conditions. Compared with the insulation monitor in the traditional medical isolation power supply system, the insulation provided by the invention not only has the monitoring function, but also has the function of locally monitoring, and can be used for visually and immediately displaying the specific failure information to a user, thus the reaction speed of the user to the relative failures of the medial isolation power supply system is increased.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an insulation monitor and a medical isolated power supply system. Background technique [0002] Medical isolated power supply system, that is, a power supply system with an ungrounded neutral point, is usually used in the medical field to provide power for electrical equipment equipped in operating rooms, ICU (Intensive Care Unit, Intensive Care Unit, etc.). It supplies power to these places through a one-way 3KVA-10KVA medical isolation transformer, which can firstly prevent the leakage current in other power supply circuits from entering the operating room, ICU and other medical electrical equipment through the ground wire, posing a threat to the safety of patients; in addition, Once the load connected to the medical isolated power supply system (such as various medical electrical equipment) has a ground fault, because the ground cannot form a loop, only a small ca...
