Topic: The importance and maintenance of protective door locks for standard instruments of electric power measurement.
Under the current background of intelligence and informationization, electric power measurement, as an important part of the national economy, plays an increasingly important role in China's economic and social development. The safety management of electric power measuring instruments, especially the anti-theft and anti-destruction of standard measuring instruments, has become one of the key concerns of the electric power industry.
First, the importance of protecting doors and locks by standard instruments of electric power measurement
1. Ensure the accuracy and reliability of electric energy metering data: As an important part of electric energy metering equipment, the accuracy of electric energy meter directly affects the economic benefits and social image of power companies, and also relates to the vital interests of the vast number of power customers. Therefore, it is particularly important for the safety protection of metering equipment.
2. Prevent human intervention and destruction: At present, there are many high-tech means in the market to interfere or modify the electric energy meter to achieve the purpose of stealing electricity. In order to avoid this situation, it is necessary to strengthen the construction of safety protection measures for key parts such as electric energy meters.
3. Meet the requirements of relevant laws and regulations: China has strict standards and specifications for power metering equipment, including GB/T 174422016 technical management regulations for electric energy metering devices and other documents, which clearly stipulate the need to install protective facilities to protect electric energy meters from external factors, and specify specific structural forms and performance indicators.
Second, the characteristics and classification of the protective door lock of the standard instrument of electric power measurement
According to the use environment and different functional requirements, the protective doors of power metering standard instruments can be divided into the following categories:
(1) Intelligent electronic lock: This type of lock adopts microprocessor control chip and sensor to realize automatic operation mode; Support remote opening and closing operation and alarm prompt functions;
(2) Physical key lock: Compared with the former, it is simpler and more practical, and the opening/locking process can be completed only by the physical key;
(3) Password keyboard lock: Users only need to enter the correct password to open the cabinet cover, which is more convenient and quick, but it also has some problems such as low security.
Third, how to do daily maintenance work?
1. Regular inspection and maintenance: according to the actual situation, make a reasonable cycle and arrange professional and technical personnel to conduct regular inspection, find problems in time and repair them to avoid minor problems dragging them into big troubles;
2. Do a good job in anti-corrosion: because it is easy to be corroded by humid air for a long time, it is necessary to take corresponding measures to prevent such situations, such as applying preservatives or making stainless steel materials;
3. Strengthen publicity, education and training: let more relevant personnel know about the popularization of safety protection knowledge, improve everyone's awareness of self-prevention, and thus better avoid the probability of risk events.
In a word, the protective door lock plays a vital role for the standard instruments of electric power measurement, which can not only effectively ensure the accuracy of electric energy counting results, but also play a good anti-theft effect. Of course, in addition to the methods mentioned above, we need to flexibly use a variety of strategies in combination with the actual situation to jointly build a more perfect and reliable security system!
