Note in the BBK / BAB explosion-proof transformer operation
(1) In the process of distribution transformers, must be regularly checked three-phase voltage balance, such as a serious imbalance, should take timely measures to adjust.
(2) regular cleaning of dirt on the distribution transformer, check the casing whether flashover discharge, the ground is good, with or without disconnection, sealing off the breakage to the regular telemetry ground resistance of less than 4 (capacity ≥ 100 kVA) or 10 (capacity of 100 kVA), or take anti-pollution measures, and install anti-pollution casing cap.
(3) then, the dissolution of the distribution transformer pinout in strict accordance with the detection process operation to avoid the pinout of the internal fracture, the wiring of the secondary side conductors to be a reasonable choice.
(4) promote the use of the new S11 series of lightning energy-saving transformer, or in the distribution transformer secondary side of the installation of surge arresters, surge arrester grounding deflectors, the shell of the transformer secondary side neutral point of common ground. Regular preventive trials, the failed arrester replacement in a timely manner, to reduce the resonance due to lightning and overvoltage damage to the transformer.
(5) no-load tap changer switch, each switch is complete, the first should be measured after two DC resistance, make a record to compare three-phase DC resistance balance. In determining the switch to normal before put into use, be measured in various stalls, in addition to, respectively, to make a record, but also pay attention to the DC resistance of the running file on the last measurement.
(6) to do the monitoring of the Taiwan area load management, and timely replacement of transformers, overload the area to prevent transformer overload operation and burn.
