Environment monitoring system of Ankrui power distribution room
At present, there are a large number of widely distributed distribution rooms of various voltage levels in China to provide safe and reliable power supply for enterprises and residents. The distribution room generally adopts the system of unattended and regular patrol inspection, which not only wastes human and material resources, but also cannot achieve real-time monitoring of the environment and safety of the distribution room. The stable and reliable environment of the power distribution room (air conditioner, fresh air fan, temperature and humidity, water leakage, fire protection, security, access control, etc.) is crucial to the normal operation of the transformer. Once a fault occurs in the environment of the distribution room that is not conducive to the normal operation of the transformer, it will affect the operation of the transformer system and pose a threat to the safe use of electricity in the distribution system. If there is no corresponding system to assist the management personnel in the distribution room, they will not be able to find the dangerous situation that endangers the equipment in the distribution room in time, nor can they take measures to avoid the expansion of losses in time, which will eventually damage the transformer equipment, and the power safety will not be guaranteed. The traditional power distribution room solution is to install their own online monitoring devices and alarm systems, independent video monitoring systems, independent security, independent access control, water immersion, gas monitoring systems for various types of electrical equipment, such as ring main units, switchgear, transformers, lines, etc., but these systems have the following problems: 1) Many data acquisition equipment and monitoring devices are not connected to the network, and can only be monitored and controlled by personnel on a regular basis. 2) Most networked systems operate independently between each other, forming an "island" phenomenon of monitoring of each subsystem. Information interaction management cannot be carried out, and the actual effect of security management cannot be achieved. When monitoring equipment and monitoring systems from multiple manufacturers are used in the power distribution room, the number of systems needed to be used and maintained by relevant personnel is more and more complex due to the incompatibility of monitoring systems from various manufacturers and the lack of a unified interface. 3) The coexistence of multiple systems not only increases the investment cost, but also the maintenance cost in the later period. In addition, the simultaneous operation of equipment and systems from multiple manufacturers will also lead to unclear responsibilities and increase the communication time and energy of owners. 4) With the technical upgrading and innovation of the power and energy industry, the equipment and systems in the distribution room will become more complex. At the same time, the operating environment and equipment status of the distribution room will also become increasingly important for the overall control of the distribution room. The intelligent monitoring of power distribution environment safety is an important part of the entire power management system. Generally, the monitoring objects are the ambient temperature and humidity of the distribution room in the low-voltage network, the status of the distribution switch, water leakage/water immersion, smoke and the anti-theft of the distribution room. The local linkage control, remote centralized monitoring and SMS alarm are performed for various parameters and statuses of the operation status of important equipment in the distribution room. The full information collection and monitoring of the distribution room is of great significance to the automatic operation management, overhaul and maintenance, disaster prevention and early warning, safety protection, power demand management and other applications of the distribution room. According to the actual situation of the distribution room, combined with years of experience in the operation and management of substations and distribution rooms, Ankeri Electric Co., Ltd. has independently developed the monitoring system platform and intelligent monitoring terminal of the distribution room of Ankeri, realizing the operation monitoring of intelligent switch cabinet, live display of high-voltage switch cabinet, load operation monitoring such as current and voltage, bus temperature measurement monitoring, cable temperature measurement monitoring Environmental monitoring, harmful gas monitoring, security monitoring, heating and ventilation, access control, lighting, fan, dehumidifier, air conditioning control and other functions. Realize the detection of various data and equipment control of the power environment, realize the optimization of the power environment, avoid the runaway operation environment leading to the operation failure of the power distribution equipment, ensure the safety of maintenance personnel, extend the service life of equipment, reduce the cost caused by extensive management of the power distribution room, and also realize the distributed remote management of the power distribution environment. The system adopts special data collector, supports wired and 4G wireless networking, has high reliability and flexible configuration, and can add functions at any time according to actual needs. In addition, the device is equipped with a touch screen to facilitate users' on-site viewing and operation. The intelligent environment monitoring platform of the power distribution room adopts technologies such as the Internet of Things and big data processing to realize online monitoring of the operating environment of the power distribution room and the status of electrical equipment, which can improve the operating reliability of the power distribution room, thus improving the operating reliability of the entire distribution network. When the expert system and data processing system of the monitoring platform analyze and find that the relevant monitoring parameters and status are abnormal, alarm information such as early warning or alarm will be sent, and remote control and other related processing can be performed.
