The distribution station area is composed of distribution transformer, low-voltage comprehensive distribution box, lowvoltage line, drop out fuse and other medium voltage protection equipment. It undertakes the important tasks of voltage transformation and power distribution in the distribution system, and its safe and reliable operation is very important to ensure the stable operation of the distribution system. With the continuous increase of load capacity, the operation environment of distribution station area is deteriorating day by day. The fire and damage accidents occur frequently in the distribution area, which seriously affect the safe and reliable operation of distribution network and have a very bad social impact. This paper takes a typical high and low voltage equipment comprehensive damage fault in the distribution station area as an example, analyzes the prominent problems existing in the low and medium voltage protection configuration, low voltage equipment installation technology, daily operation and maintenance management, etc. The case has high learning value and significant guiding significance. It basically covers the outstanding problems in technology, technology and management of the current distribution area. Through in-depth analysis of the case, targeted and reliable solutions are proposed, which can effectively improve the operation level of distribution network.
