How to improve the safety and stability of hospital building electrical design?

The Importance and Particularity of Electrical Design of Hospital Buildings

As a special key public building, the hospital building is different from many other public buildings and has special standards for electrical design. Due to the large number of assembled and complex electrical facilities in the hospital, the frequency of use is extremely high, and the electrical facilities are required to have high reliability and safety during actual use. The electrical devices involved include high-voltage/low-voltage power distribution systems, Power generation systems, inverters… High-quality operation and safe operation of hospital electrical equipment are essential. Therefore, starting from the preliminary design and planning of the hospital building project, in addition to complying with the relevant requirements of the “Code for Electrical Design of Medical Buildings” formulated by the state, the long-term safe operation of the electrical facilities of the hospital building must also be considered. At the same time, considering the maintenance and renewal of the hospital’s electrical facilities in the later stage, the hospital construction project must provide standard and detailed electrical design and electrical calculation report documents when the project is established and delivered.

Existing Problems in Electrical Design of Hospital Buildings

Hospital construction projects are generally outsourced, including electrical installation and electrical calculation selection. In the process of design and implementation of building electrical engineering, due to the lack of collaboration among hospitals, engineering companies, construction parties, and maintenance units, they participate in the entire life cycle of the project, and the complexity of the hospital construction project itself is very large. To a certain extent, it will lead to many mistakes and defects in the electrical design and calculation data of the entire project, such as the distribution of high and low voltage distribution systems, the selection of transformers and relays, and so on. These problems not only lag the progress of the project, but also cause potential safety hazards in the future use of electrical facilities, which will bring immeasurable consequences to the hospital.

Generally, when the project is delivered, in many cases, only all or part of the technical documents for the installed electrical facilities are provided, such as schematic diagrams, technical parameter tables, etc. For the hospital side, it is difficult to grasp all the technical information of the project. When the hospital faces the maintenance, update, or third-party testing of electrical facilities in the future, these data cannot be used as a reference due to lack or inaccuracy, and they have to re-outsource technical services, which increases labor and costs. In the end, technical outsourcing again does not mean that complete technical information can be obtained.

The trend of green energy saving in the electrical design of hospital buildings

We know that the demand for electricity in hospitals is extremely huge, so the consumption of electricity is also huge. Because of this, how to make the hospital fully realize the development goal of “green energy saving” on the premise of ensuring the normal operation of the electrical system has become an important issue that needs to be faced and considered in the development of modern hospital building design.

With the rapid development of information technology, computer software technology has been widely used in hospitals. This has also become a help for the hospital to achieve “green energy saving”. To achieve “green energy saving”, in the electrical design process of each link, it is necessary to calculate a lot of relevant data, such as short-circuit current, protection diagnosis, etc., and these can now be accurately calculated through electrical calculation software. It can ensure the continuity and safety of power supply, and on the premise of ensuring normal operation, plan a scientific and reasonable energy consumption control and energy saving mode to reduce the waste of hospital energy consumption.

Application cases in foreign hospitals

At CHU de Rennes in France, the electrical department and subcontractors responsible for the construction of the hospital completed the construction of the hospital’s new emergency center in accordance with the relevant requirements stipulated in the electrical calculation regulations. From the very beginning of the construction project, eleccalc electrical software was introduced for electrical design and calculations for the entire project. Rennes Hospital has a building area of ​​300,000m², a total of 65,000 lamps, 55,000 sockets, and 120 high and low batteries. The electrical system consists of 17 substations with a total installed capacity of 22MVA, 15MVA generators, and 19 inverters. It is critical for the facility to function properly. After applying eleccalc, Locï Bardou, head of the hospital’s electrical department, said: “For the hospital, the reliability and stability of the power supply is of the utmost importance, and eleccalc helped us to do that.”

meet the actual needs of the hospital

• Accurate electrical calculation and analysis data, shorten the project design cycle and save costs.

• Huge computing and analysis capabilities ensure the stability and safety of power facilities in the project.

• Real-time fault alarm, quickly lock the power fault range and fault cause.

• Adopt multi-standard management when upgrading old buildings to ensure normal operation.

• New facility planning to achieve green energy conservation, make full use of energy, reduce energy waste and save energy costs.

Electrical Computing Solutions for Green Building Design

The Eleccalc mentioned in the above practical application is a building electrical solution developed by the French Trace Software Group that runs through the entire life cycle of the project. It not only includes ordinary public construction projects, but also can be used for construction projects of important facilities, such as hospitals, data centers and other facility projects. Eleccalc can perform computational analysis of complex electrical systems, verify and optimize the safety of electrical systems.

Not only in France, but also in China and even other countries. Because it supports multi-national design standards (IEC, NF, etc.), it has been translated into many languages ​​(English, French, Medium).

It not only supports the design calculation and analysis of new facilities, but also applies to old buildings and facilities that need to be renovated. Through multi-working mode management, multiple power supply working modes can be simulated to ensure safe and reliable operation in a comprehensive environment.

Not only do the calculation and safety analysis of the protection device, but also the most economical and energy-saving design can be planned to reduce energy consumption and improve the utilization rate of energy while ensuring the normal working state of the system.
