Waterproof detachable current transformer

Abstract

The invention discloses a waterproof detachable current transformer. A first groove is formed in a first box; a first iron core is fixed in the first groove in a sealing manner; a second groove is formed in a second box; a second iron core is fixed in the second groove in a sealing manner; a first module and a second module are mounted at the two ends of the first iron core on the first box respectively; a first module and a second module are mounted at the two ends of the second iron core on the second box respectively; when the first box and the second box are detachably fixed together, the first module on the first box is fitted with the second module on the second box, and the second module on the first box is fitted with the first module on the second box; a waterproof joint is mounted on the second box; and an output electric wire is mounted in the waterproof joint and extends into the second groove to be electrically connected with coils. The waterproof detachable current transformer provided by the invention is waterproof, dampproof, shock-proof and break-resistant.

Description

technical field [0001] The invention belongs to a circuit induction device, relates to a current transformer, in particular to a waterproof detachable current transformer. Background technique [0002] Current transformers are used in the field of automation control to detect current. The traditional current transformer has a closed structure, which needs to disassemble the busbar, and the installation is often inconvenient. Although there are also separated current transformers on the market, this kind of separated current transformer can detect the current on site without powering off and removing the primary busbar, but this kind of separated current transformer is not waterproof and is not suitable for outdoors, because if If it is used outdoors, water will enter the interior of the separate current transformer, which will cause damage to the internal devices, such as a short circuit of the coil, and burn the entire device. In addition, the two boxes of this separated ...

The traditional current transformer has a closed structure, which needs to disassemble the busbar, and the installation is often inconvenient

Although there are also separated current transformers on the market, this kind of separated current transformer can detect the current on site without powering off and removing the primary busbar, but this kind of separated current transformer is not waterproof and is not suitable for outdoors, because if If it is used outdoors, water will enter the inside of the separate current transformer, which will cause damage to its internal devices, such as a short circuit of the coil, and burn the entire device

In addition, the two boxes of this separated current transformer are fixed together by simple buckles, and the fixation is not firm enough. When the separated current transformer is lightly dropped on the ground, the two boxes will fall apart and separate
