Static Power has developed and manufactures a DC chop-over box to facilitate the prompt provision of temporary power to substations in the event of failure of the Substation DC system.
Tony Gordon, Manager, Technical Sales, of the business unit, which has been providing DC back-up power solutions for substations for many years, said the new product will also prove highly safe and convenient as a temporary power connection into the existing substation DC system during breakdowns or when the station battery is capacity tested at site

“The chop-over box, known as the DCC7 box, has been developed to act as the interface between a substation DC system and an external battery trailer that can be towed to the site. The trailer contains a backup battery and charger together with a permanently built-in battery discharge unit,“ he explained.
”The DCC7 box is mounted on the outside of the substation, with the substation DC wired to it.
This provides quick and safe access to the substation DC system whenever a temporary DC system is required via supply from the battery trailer. It is simply a matter of plugging it into the DCC7 box and switching it on.”
The DCC7 box is IP65 rated and is equipped with a weatherproofing flap over the plug connection points to prevent weathering and corrosion of the plug terminals.
