Volyn: CIPB scientists have developed a device for emergency disconnection of residential buildings and structures "SPORT"
One of the stages of operative actions of fire and rescue subdivisions during fire extinguishing is blackout about’object. To perform the specified operation rescuers armed with special dielectric tool – a dielectric scissors. Their application is regulated by the Charter to the actions in emergency situations and safe work practices. Since the main application of shear is pageline cut the wires for voltage up to 220 V, they cannot be used in modern conditions. In 2006, the rules of device of electrical equipment have been amended. One of the innovations was the requirement, which is that lines of electric networks, which are reconstructed or are under construction in the residential sector, must be implemented zamotannym insulated wire (SIW). Such innovations rescuers were not ready, and the service control element of the emergency switch is not provided. “the Transition to the use of wires, SIP due to the new requirements of the European standards to ensure a common space with the European electricity grid. This type of wire has several advantages in comparison with wire marks And and AC. He intertwined excludes the possibility of injury to a person by electric shock in case of fall or breakage and more» – told the seminar honored power engineer of Ukraine, Otroshko Mikhail. He also added that the issue of protection of lines of electric networks are also taken into account. It fuses, circuit breakers, voltage relays and differential machines. Latest device protects the network from short circuit, and transient resistance, so if any water gets to energized equipment, it will work immediately and spectrumit all about’object". The above mentioned protection system, and placing circuit breakers on the outside of the building does not meet fire rescue units, because there are cases when it is necessary to disconnect the building from outside. This factor is especially present in rural areas. The remoteness of fire and rescue units leads to an increase in time of fire development, and, often, at the time of arrival of rescuers the building covered by flame ' pits. In this case, turn off the circuit breaker outside of the building does not eliminate the likelihood of water. It is such a real situation, and encouraged the scientists of the Institute to develop a means of de-energizing buildings, which are made insulated wires. The basis for the development put: safety for the person doing the disconnection, mobility and efficiency in use, and also avoid the possibility of emergency operation mode of the electrical network.
