    摘要: A contact-making device (10) is used for a resistance measurement on a test object (30). The test object (30) comprises a threaded hole (31), which has an internal thread (32). The contact-making device (10) is designed to be mechanically coupled to the internal thread (32) of the threaded hole (31). The contact-making device (10) comprises a first contact (11) and a second contact (12), in order to make electrical contact with the test object (30) at, at least, two points when the contact-making device (10) is mechanically coupled to the internal thread (32). The first contact (11) and the second contact (12) are electrically insulated from one another by an insulating material (15-17) in the contact-making device (10).

    摘要: The invention relates to a test system and a method to test a circuit breaker (2) of an electrical switchgear assembly. A sub-station battery (3) of the electrical switchgear assembly is used to generate a supply voltage (7) for the circuit breaker (2) for the testing thereof, wherein the sub-station battery (3) is coupled to a test device (1) in order to generate the supply voltage (7) for the circuit breaker (7) [sic] from an input voltage (6) provided by the sub-station battery (3). The supply voltage (7) is stabilized by means of a voltage regulator (11) of the test device (1).

    摘要: An apparatus and method for the measurement of a resistance of a switching contact of an electrical circuit breaker. A first resistance value across the circuit breaker is determined while the circuit breaker is grounded at both sides and the switching contact is closed. Further, a second resistance value across the circuit breaker is determined while the circuit breaker is grounded at both sides and the switching contact is open. The resistance of the closed switching contact is then determined based on the first resistance value and the second resistance value.

    摘要: The present method relates to a method for checking a multi-pole electrical circuit breaker. The multi-pole electrical circuit breaker comprises a plurality of poles (101-103). Each of the plurality of poles (101-103) comprises a first connection (121-123) and a second connection (131-133). Closing the particular pole (101-103) makes it possible to electrically connect the first connection (121-123) of the particular pole (101-103) to the second connection (131-133) of the particular pole (101-103) via the pole. In the method, a plurality of micro-ohm measurements are carried out at the plurality of poles (101-103), while the plurality of poles (101-103) are earthed on both sides in a P-P-P-E configuration. A contact resistance of one of the plurality of poles (101-103) is determined on the basis of the plurality of micro-ohm measurements.

    摘要: Measuring device for checking an electrical circuit breaker includes a current generating unit designed to generate a measurement current for a continuity measurement of a switching contact of the circuit breaker. The measuring device furthermore includes a measuring unit for registering a measurement signal at the circuit breaker, an energy supply unit for supplying a control drive of the circuit breaker with electrical energy, and a control unit, which has a timer. The control unit is able output to the control drive, via the control output, a signal for opening or closing the circuit breaker, and to determine a time-based switching behaviour of the circuit breaker in dependence on the measurement signal. Further, the control unit is designed, in the case of the circuit breaker being closed, to determine the resistance of the switching contact in dependence on the measurement current and the measurement signal.
