Problems solved by technology
[0003] The operating environment of the substation is relatively complex. The conventional secondary equipment of the substation, the power module and various functional electrical modules are installed in one piece. The power module occupies a certain amount of space in the chassis. More serious, it is easy to cause the internal temperature of the secondary equipment to be too high, which will affect the stability of the secondary equipment; on the other hand, the anti-electromagnetic compatibility ability of the power module itself needs to be improved, which will also affect the stable operation of the secondary equipment

The invention relates to the technical field of automation of a substation of an electric power system, specifically to a secondary equipment apparatus. A power supply module of the secondary equipment apparatus is arranged in a power supply module shell; the power supply module shell is arranged on the exterior of a machine case, so that the power supply module can be independently arranged on the exterior of the machine case; therefore, influence to normal operation of other electrical modules in the machine case from heating of the power supply module can be avoided, electromagnetic interference of the electrical modules to the power supply module also can be avoided, and the stability of the secondary equipment is improved; the power supply module is arranged on the exterior of the machine case, so that when operation failure warning occurs to the power supply module, the power supply module can be replaced simply and rapidly, and power cut time caused by the power supply module failure can be greatly shortened; meanwhile, by virtue of the independent setting of the power supply module, operation to the power supply module in the later-period overhaul and maintenance also becomes convenient; and when the secondary equipment has a failure and needs to be replaced, the power supply module can be reserved, so that the maintenance cost and replacement cost are lowered.
Description
technical field [0001] The invention relates to the technical field of power system substation automation, in particular to a secondary equipment device. Background technique [0002] With the full development of smart substation construction and the rapid development of smart substation technology, future substation equipment will have the technical characteristics of "standardized design, modular combination, factory processing and intensive construction". In order to enhance the scalability of the system, the substation equipment will adopt a "plug and play" standardized interface design. The standardized design and plug and play of all interfaces of the secondary equipment will effectively solve the maintenance and expansion of smart substations. The difficulty of equipment can quickly and simply complete the installation, commissioning, and upgrading, and achieve the effect of easy maintenance, less maintenance or even maintenance-free, thereby improving the constructio...
