What is a Medical-specific Voltage Stabilizer?
As a public power grid, the power supply system is connected to thousands of various loads, including some large inductive, capacitive, switching power supplies and other loads. These loads not only obtain power from the power grid, but also affect the power grid itself, causing distortion of the mains voltage waveform or frequency drift, making the power grid worse and reducing the power supply quality of the power grid.
In addition, natural accidents and man-made accidents, such as excessive load voltage, open circuit or short circuit of power transmission and transformation system, earthquake, and lightning strike, will endanger the normal supply of electricity, thereby affecting the normal operation of the load. At this time, a voltage stabilizer is required to maintain the stability of the output voltage.
The Importance of Voltage Stabilizer in Medical Equipment
Almost all medical equipment needs to be powered by electricity. In addition to medical equipment related to the technology and performance of the machine itself, the normal supply of electricity is also crucial. The normal use of medical equipment is related to the life of the patient, and a slight misstep can cause irreversible results.
The stability and reliability of power supply are related to the lifeblood of patients. Advanced equipment also poses challenges to power supply. During the use of medical equipment, there will be problems such as inability to work under DC and AC, electrical failure, inability to start, and output. Alarm failure, leakage, burns, button failure and other phenomena caused by equipment also occur frequently. Therefore, in this case, a special voltage regulator for medical equipment is generally used to maintain the stability of the output voltage. However, as long as it is a voltage stabilizer, it can be regarded as a special voltage stabilizer for medical equipment, but a voltage stabilizer that meets the requirements of medical equipment is a high-quality voltage stabilizer among the voltage stabilizers.
Technical Sandards for Voltage Stabilizer in Medical Equipment
For medical-specific voltage stabilizers, the following conditions must be met and guaranteed:
- The voltage stabilizer for medical equipment must be high-precision first. The higher the voltage stabilization accuracy, the more stable the operation of the medical equipment.
- Medical-specific voltage stabilizer must also be maintenance-free, no mechanical operation voltage stabilizer, because if the medical equipment is working and the voltage stabilizer has a mechanical failure, we all know that the mechanical failure will occur only in the equipment with mechanical action (For example, carbon brush regulators are mechanically operated regulators, also called contact regulators).
- The special voltage stabilizer for medical equipment must also be three-phase stabilizer, which is not a rigid requirement, but only from the consideration of hospital space and cost. The voltage stabilizer with three-phase sub-adjustment function can be connected to three-phase equipment and single-phase equipment at the same time. It is not necessary to separate the three-phase electrical equipment from the single-phase electrical equipment and purchase a special voltage stabilizer for single-phase medical equipment and the three-phase electrical equipment separately.
- The anti-interference ability is also a rigid requirement of the voltage stabilizer for medical special equipment.
- Protection functions such as overvoltage, undervoltage, short circuit, phase loss and automatic bypass are also indispensable conditions for medical equipment.
A voltage stabilizer that meets above requirements must be a non-contact voltage stabilizer. The non-contact voltage regulator has the characteristics of fast voltage stabilization, high voltage stabilization accuracy, three-phase sub-adjustment, anti-interference, and multiple protection functions. In the voltage stabilization work, there shall be no mechanical operation and no maintenance.
