Abstract

An anti-theft locking device of a power transformer belongs to the field of a power system, which is used for solving the problems that the mechanical anti-theft effect of an existing power transformer is limited and an electronic monitoring anti-theft technology cannot be used for effectively preventing a site theft behavior of a thief. In the scheme, a first L-shaped locking plate, a second L-shaped locking plate, a third L-shaped locking and a fourth L-shaped locking plate are used for sequentially clamping a transformer shell and four side edges of an upper cover of the transformer, a locking bolt plate is used for locking or opening the fourth L-shaped locking plate and the first L-shaped locking plate from inside, the locking bolt is controlled to move through on-off of two groups of electromagnets, power is supplied to the electromagnets by a storage battery, and the storage battery adopts a wireless mode to charge. In the locking device, weak bolt and nut structures are packaged, the locking device forms a round locking force, an attack force which can be resisted is very large, the locking device cannot be forcedly opened through a small-sized tool by the thief, and perfect anti-theft protection on a field power transformer is achieved.

Description

technical field [0001] The invention relates to the field of power systems. Background technique [0002] Transformers are important equipment in the power system and play a vital role in the transmission and distribution of electric energy. However, many power transformers are installed in the open outdoors and use unattended mode. There are often thefts during operation. Risk, some criminals destroy and steal transformers, and sell the copper core coils as scrap copper to make a profit. The destruction and the theft of copper coils caused huge losses to national property and industrial and agricultural production. Therefore, the safety protection of power transformers is an urgent problem to be solved by the power sector. [0003] At present, the anti-theft technology for transformers is mainly divided into two categories: one is the mechanical structure, and the other is the electronic monitoring remote alarm module. [0004] The first type of anti-theft technology mai...
