型号含义

MHT
Floor mounted metering box of Huatuo group Rated voltage:12kV

 

Working conditions
◊ ambient air temperature: - 40 ℃ ~ 40 ℃;
◊ maximum daily temperature difference: 25 ℃;
◊ altitude: ≤ 1000m;
◊ pollution level: level IV;
◊ places without flammable, explosive and chemical corrosion;
◊ this product has the advantages of convenient installation in structure, beautiful appearance and small occupied area. It is a perfect combination of living quarters, industrial and mining enterprises and box transformer;
◊ when the equipment is electrified, the high-voltage room cannot be opened for operation. The door of the high-voltage room can be opened only in case of power failure, which is safe and reliable;
◊ lighting lamps shall be installed in the incoming room and outgoing room. Transparent observation windows are installed on the left and right sides above the instrument room, which can observe the interior of the incoming and outgoing rooms respectively. Personnel can directly open the door to check the bottom of the meter and operate the switch locally;
◊ the transformer adopts fully enclosed epoxy resin vacuum pouring, so the aging problem is eliminated;
◊ the dividing switch part adopts zw43 column circuit breaker with protective current transformer to realize zero sequence, overcurrent and quick break protection with intelligent controller, which can automatically remove single-phase grounding fault and automatically isolate phase to phase short-circuit fault.
