As a unique area, hospitals use a lot of electrical engineering. Through the data collection and big data analysis platform of various electrical equipment in the hospital clinic, centralized and real-time diagnosis of various electrical parameters of electrical equipment is carried out, and based on the standard values and specific values of various electrical equipment parameters Comparing parameters such as value and running time to adjust and calculate. , it is convenient to draw the deterioration map of electrical equipment components, adopt early warning information countermeasures, and immediately eliminate hidden dangers.
The regulations on the power supply and distribution system of contemporary large and medium-sized general hospitals are not limited to the applicability and reliability of power supply, but the real-time power, power supply quality, leakage current and main line temperature of power distribution equipment can be intelligently monitored, and the main parameters of electrical equipment can be observed. changes and various anomalies. In addition, the maximum value of the parameters limited by the system can detect various potential safety accidents in advance, and can also contact the manufacturer for free online to solve common fault points in time, improve maintenance efficiency, and make The traditional power supply and distribution system is more intelligent and professional.
The second is the setting conditions and power supply range of the emergency power supply. Article 3.0.3 of our company’s standard GB50052-2009 “Code for Design of Power Distribution System” stipulates that an emergency power supply should be added to the particularly important load in the first-level load, and the emergency power supply system is dedicated to the particularly important load in the first-level load. Access other loads. However, JGJ312-2013 “Electrical Design Standards for Medical Buildings” expands the function of EPS emergency power supply and the scope of power supply system to “general medical treatment process and hospital fire evacuation”, which violates the “prohibition of connecting other loads to EPS emergency power system software” ” Mandatory requirements.
The load on hospital buildings has become more complex. Air conditioners, computers, UPS power supplies, etc. not only increase the pulse current, but also show fluctuation characteristics. So far, fixed capacitance compensation or capacitor banks with contactors disconnected are generally used in buildings, but in high harmonic environments, it is difficult for such existing compensation devices to respond to compensation requests, and the existing capacitance compensation devices amplify Higher harmonics are affected by the safety of the compensation device itself.
User Value of Reactive Power Compensation and Harmonic Control
Reactive power up to standard, avoiding power factor penalty;
Energy saving
Inhibit the influence of harmonics and prolong the service life of electrical equipment in the building.
Problems you may encounter?
1. There are many single-phase loads. Single-phase load will cause zero-sequence pulse current, and will cause three-phase unbalance and three-phase phase difference.
2. The proportion of nonlinear load is high, and the harmonic distortion rate of harmonic source is large.
3. Many intelligent and automated equipment in building power distribution have high requirements on power supply quality, especially sensitive to harmonics.
Our solution:
1. Use the company’s static safety compensation device to compensate the reactive power of the system, and reasonably configure the reactance rate according to the harmonic conditions of the system to prevent harmonic amplification;
2. The Hongyan static safety compensation device adopts a mixed compensation method of three-phase compensation and separate compensation to meet the compensation requirements of the three-phase imbalance of the system;
3. The mixed use of active filter 2000 and static safety compensation device Hongyan TBB can solve the harmonic influence of the municipal government power distribution system, reduce system loss, and make the power distribution system run safely and efficiently, especially for electrical safety requirements It makes more sense for very high users.
