The utility model relates to a power equipment, harmless ground connection distrbution transformer platform of bilateral promptly, also including being by becoming platform, high -pressure side, transformer, low tension side, the different is: the high -pressure side is equipped with high -pressure ground wire and articulates the ware, the low tension side is equipped with low pressure ground wire adapter, high -pressure ground wire wherein articulates the ware has the high -tension bushing who is connected with the high -voltage line, high -tension bushing supports one in the top and articulates the ring, the high -tension bushing below is equipped with insulating cluster, insulating cluster lower extreme is installed on high piezoelectric cylinder's cross arm through linking the board, low pressure ground wire adapter sets up low -pressure cabinet below the transformer, installation air switch and doublethrow switch in the low -pressure cabinet, doublethrow switch itself meets with the low tension side, upwards the load side with the transformer contacts, downward and low pressure ground line terminal contacts. The beneficial effects are that: during the operation, can satisfy the requirement that becomes the two side joint ground of platform operation, improve the security performance, characteristics such as just have simple structure, convenient operation, the installation of being convenient for, save material, occupation of land are less.
