Small high-frequency induction heating equipment
should have high reliability technical index, and the reliability index can be measured by the Mean Time Between Failures(MTBF). High-frequency induction heating equipment is a special power source in power supply category. Therefore, its reliability index can be stipulated in the general power standard. MTBF is great than or equal to 3000 hours, that is to say, Mean Time Between Failures must not be lower than 3000 hours.
Safety requirements: The design of small high-frequency induction heating equipment should meet the safety requirements of relevant standards or product specifications such as insulation requirements, electrical strength requirements, anti personal electrical contact requirements and so on, in order to prevent power failure or danger of personal and equipment under extreme conditions and bad environment conditions.
Maintainability requirements: The maintainability requirements can be measured by the Mean Time Between Failures(MTBF). The small high-frequency induction heating equipment with good maintainability should have the following characteristics.
First, the power supply design has the function of fault self diagnosis. When the power supply fails, it should be able to diagnose the fault phenomenon and location in time according to the alarm display.
Second, The functional components of the power supply should be standardized, modular and integrated. When the power supply fails, the fault components can be replaced in a short time without the proprietary tools or high technical level person, and the fault is excluded in order to ensure the power supply to run again in time.
The high cost performance requirements of induction heating power supply and low cost of use and maintenance: High performance price ratio is the goal pursued by both of us and users. It is also an important issue that we must pay close attention to under the market economy.
Small high-frequency induction heating equipment should be suitable for environment, and the requirements for environmental conditions are relatively loose. The environmental suitability requirements mainly refer to the requirements for the environmental temperature, humidity, altitude and the cleanliness of the surrounding environment, as well as the requirements for the power quality of the power grid.
High power density: The heating equipment should have the high requirements of power capacity per unit volume(w/cm2) and power capacity per unit mass(W/g) so as to reduce the volume and mass of the power equipment, and it is easy to install and use in less land occupation. In order to achieve high power density requirements, we must carry out reasonable design, adopt advanced switching circuit technology, correctly use raw materials, reduce power loss and so on.
