No. 47 Yulin Power Supply Bureau 110KV substation put into operation
In order to meet given the rapid economic development side, to meet the industrial and agricultural production and
people s lives Dingbian growing demand for electricity, the western power grid to optimize the structure of Yulin, after
four months of intense construction of the building, at 22 o clock on September 23, 110KV be operational change while
Zhang Liang, Yulin Power Supply Bureau is put into operation the first 47 110KV substation.
Zhang Liang 110KV change is the hub of the western power grid substation planning, it can greatly improve the
construction of the western power grid network structure, the western power grid to solve the main problems, increase
the system s load capacity, improve the system reliability, reduce line losses improve power quality. Currently, the
western grid s load capacity has reached its limit, according to the load forecast, 5 years have 130MW of new power load
changes by Zhang Liang.
Zhang Liang 110KV substation installation of 2 × 50MVA final three-winding on-load tap changer, a 31.5MVA current
transformer, in order to better meet the user requirements for power quality, the main transformer using low-loss, a
longer maintenance cycle of the three phase three-winding self-cooled hermetically sealed load tap; 110KV double-bus
connection, end-of-12 back into the outlet, the current 6 back; 35KV single busbar connection, end-of-6 back into the
outlet, the current pre- stay; 10KV single bus segment wiring, terminal into the outlet 16 back, the current 8 back.
Zhang Liang 110KV 110KV transmission project by the Zhang Liang and Zhang Liang substation 110KV salt brick line change
to π then double-circuit transmission line components, project design, construction completed by their own power supply
bureau in Yulin, a total investment of 34.87 million yuan. The project is "Yulin Energy and Chemical Base" 2 +6 "network
planning" project, 110KV Zhang Liang change put into operation for the coordination of regional development, to achieve
leapfrog development set while creating the economic conditions, to accelerate local economic growth, for local people
to get rich as soon as possible to provide a strong power protection, with a very clear social benefits.
