Product Overview
The floor standing measuring box is a product that replaces the high-voltage measuring, switching, and control box on the column with a cabinet structure.t is composed of ZW43 column mounted circuit breakers, measuring voltage transformers, measuring current transformers, and other components. The box is made of stainless steel material and is divided into an inlet room, an outlet room, an instrument room, and a handle operation room.

Working Conditions

Surrounding air humidity:-40°C~40°C;Pollution level:Level IV
Maximum daily temperature difference: 25 °C;Altitude: not exceeding 1000m
Places without flammable, explosive, or chemically corrosive hazards

Product Feature

This product is structurally easy to install, aesthetically pleasing, and occupies a small area.It is a perfect combination product for use in residential areas, industrial and mining enterprises,and box type substations.
When the equipment is live, the high-voltage chamber cannot be opened for operation. Only in the event of a power outage can the high-voltage chamber door be opened, which is safe and reliable.
Install lighting fixtures in the incoming and outgoing rooms. There are transparent observation windows installed on the left and right sides above the instrument room, which can respectively observe the inside of the incoming and outgoing rooms. Personnel can directly open the door to view the bottom of the meter and operate the switch action on site.
The transformer adopts fully enclosed epoxy resin vacuum casting, thus eliminating aging problems.
The boundary switch section adopts ZW43 pole mounted circuit breakers with protective current transformers,which can achieve zero sequence, overcurrent, and quick break protection with intelligent controllers. It can automatically cut off single-phase grounding faults and isolate phase to phase short circuit faults.
