The shunt is mainly composed of manganese copper sheet and copper joint welding. There are two groups of terminal buttons on the joints at both ends of the shunt: the outer group is the potential terminal button for connecting with the power line, and the inner group is the potential terminal button for connecting with the measuring instrument.Description of fixed fixed value shunt:Purpose: fixed fixed value shunt is a kind of external shunt which can directly act on the analog display instrument when the measured DC current is less than 10kA. It can also be regarded as the standard resistor for current sampling in sequential circuits. The sampling voltage can be regarded as the analog signal of primary current for measurement.1、 Main technical parameters:. Accuracy level: 5 ~ 4000A; 0.5: 5000 ~ 10000a: Grade 1.. Environmental conditions: - 40 ～ + 60 ℃, relative temperature ≤ 95% (35 ℃).. Overload performance: rated current 120%, 2 hours.. Voltage drop: 50mv60mv75mv100mv. Heating under load: after the temperature rise tends to be stable, the rated current below 50A shall not exceed 80 ℃, and the rated current above 50A shall not exceed 120 ℃.. Mechanical resistance: it can withstand the transportation bumps with acceleration of 70 m / s and impact frequency of 80 ~ 120 times per minute for 6 hours.2、 Scope of applicationThe shunt is widely used to expand the measuring current range of the instrument, and can be used for the current limiting, current sharing, sampling and testing functions for the circuits of communication system, electronic whole machine, automatic control power supply, etc. the service condition is group B.3、 Precautions、 No artificial contact resistance is allowed at the connection between the cable (or copper bar) of the primary circuit of the shunt and the shunt, and the sampling point of the secondary voltage cannot be sampled from the non sampling point.、 It is recommended that the actual current used (for a long time) should not exceed 80% of the rated current.
