DROP STATUS INDICATOR

Structural features

It is generally composed of transformer body, fixed mechanism and electrical warehouse. The instrument transformer body comprises a lower shell and an upper shell that are hinged with each other, and a core induction core that is connected with the ends is installed inside, and is hinged and connected to form a cable slot to cover the arc elimination tube and other components. The fixing mechanism includes a clamp or expansion module, which is used to fix the transformer on the arc extinguishing tube, and also includes an elastic clamp, etc., which can detect the working temperature and current of the arc extinguishing tube. A circuit board and a mercury switch type sensor connected with the circuit board are arranged in the electrical warehouse.

Product overview

Product overview

BYWM current transformer is mainly used for cable and copper bar, its structure is simple, reasonable design, flexible application, and according to the main circuit used in the cable copper bar specifications have a variety of core aperture corresponding, the main circuit primary current contains 50A~6000A, rated secondary output current IA~5A[0~1V]. This series of products can meet the technical requirements of 0.2, 0.5, 1 and other different precision. This product complies with standards: GB/T 20840.1.2, IEC 61869-1 and IEC 61869-2.

Working principle

The status of the transformer is sensed through the built-in mercury switch sensor and other devices. When the transformer is in the normal position, the mercury switch is in a specific state and the circuit is in a certain stable state; and when the installed arc suppression tube falls due to a blown fuse or other reasons, the state of the mercury switch changes, thereby triggering a change in the circuit. This enables the transformer to send out corresponding drop signals through wireless signals, etc., so that staff can locate and judge faults.
