Description
Technical Field
The utility model relates to an electromagnetic trip, concretely relates to high sensitive electromagnetic trip.
Background
The electromagnetic release is one of releases, only provides magnetic protection, namely short circuit protection, and actually is a magnetic return force, and when the current is large enough, the generated magnetic field force overcomes a counter spring to attract an armature to strike a traction rod so as to drive a mechanism to act and cut off a circuit. The existing electromagnetic release is unreasonable in structural design, does not have a release adjusting device, cannot achieve the release adjusting function of the electromagnetic release, is single in function and insensitive in release action, and further has the defects of unreliable performance, complex structure and inconvenient assembly.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, the convenient high sensitive electromagnetic trip of assembly.
In order to achieve the purpose, the utility model adopts a high-sensitivity electromagnetic release, which comprises a shell and a release mechanism, wherein the shell comprises a base and a cover cap arranged on the base, and an accommodating cavity is formed between the base and the cover cap, the tripping mechanism is arranged in the accommodating cavity and comprises an L-shaped yoke arranged on the base, an iron core arranged on the L-shaped yoke, a coil frame sleeved on the iron core, a coil arranged on the coil frame, a yoke arranged on one side of the L-shaped yoke corresponding to one side of the coil, a magnet arranged between the L-shaped yoke and the yoke, an armature movably arranged on the yoke corresponding to the upper part of the coil, and a tension spring, the base is provided with a tripping adjusting component, one end of the tension spring is connected with the tripping adjusting component, the other end of the tension spring is connected to one end of the armature, and a tripping hole is formed in the position, corresponding to the upper portion of the armature, on the cover cap.
The beneficial effect of above-mentioned structure is: the electromagnetic release has the advantages of simple structure, stable and reliable performance and convenient and fast assembly. The cover cap is provided with a tripping hole, the tripping rod can pass through the tripping hole and abut against the armature, when the electromagnetic tripping device works, the coil is electrified, the iron core generates magnetic force to drive the armature to act, and the armature pushes the tripping rod to act, so that the tripping action of the electromagnetic tripping device is realized.
Particularly, the dropout adjusting part including set up adjusting screw on the base, set up arm-tie on adjusting screw, set up the shell fragment between arm-tie and base, the one end of arm-tie be provided with T type joint portion, the one end block of extension spring in T type joint portion, and constitute the joint cooperation of arm-tie and extension spring. The base is provided with a tripping adjusting component, and the elasticity of the tension spring can be adjusted by rotating the adjusting screw, so that the tripping sensitivity and the tripping precision of the electromagnetic tripper can be improved.
