Problems solved by technology
In normal work, two sets of electromagnetic releases with different functions are often used to achieve two tripping actions, one of which is a current-type electromagnetic release and the other is a voltage-type electromagnetic release. The buckle has an independent casing and setting and the action components in the casing, resulting in crowded space in the distribution box and complicated installation due to the two occupying too much space

The invention relates to a double-action electromagnetic release which comprises a framework, a current coil, a voltage coil, a static iron core, a first movable iron core, a second movable iron core and a mandrel used for being linked to other mechanisms for releasing. An installation cavity is arranged in the framework. The static iron core, the first movable iron core and the second movable iron core are installed in the installation cavity in sequence. The static iron core is fixedly installed in the installation cavity; the first movable iron core and the second movable iron core are installed in the installation cavity in a sliding mode. The current coil and the voltage coil are fixedly arranged on the outer periphery of the framework. The framework, the static iron core and the first movable iron core are coaxial, are provided with supporting holes respectively, and form a sliding cavity of the mandrel. The mandrel is composed of an inner mandrel and an outer mandrel. A mandrel cavity for axial sliding of the inner mandrel is arranged at the center of the outer mandrel. The end of the inner mandrel facing the second movable iron core is linked to the second movable iron core. The end of the outer mandrel facing to the first movable iron core is linked to the first movable iron core. The double-action electromagnetic release is quick in response and high in sensitivity.
Description
technical field [0001] The invention relates to a release, in particular to a double-action electromagnetic release. Background technique [0002] A trip unit is a device installed on or integrated with a circuit breaker to release the holding mechanism and automatically disconnect the circuit breaker. In normal work, two sets of electromagnetic releases with different functions are often used to achieve two tripping actions, one of which is a current-type electromagnetic release and the other is a voltage-type electromagnetic release. The buckle has an independent casing and the setting and action components in the casing, which cause the space in the distribution box to be crowded and the installation complicated due to the two occupying too much space. [0003] In order to solve the above problems, the patent document with the application number CN201310297844.2 discloses a double-action electromagnetic release, including a skeleton, a current coil, a voltage coil, a sta...
