Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] see Figure 1-3 , a ventilated circuit switch capable of circuit protection, comprising a switch box 1, an upper vent 28 is opened on the front side of the switch box 1, a lower vent 20 is opened on the rear side of the switch box 1, and the inside of the lower vent 20 Through the transition piece, heat dissipation blades 29 are fixedly installed, which can effectively dissipate heat in the switch box 1. The upper end of the switch box 1 is provided wit...

The invention relates to the technical field of circuit protection, and discloses a ventilation type circuit switch capable of circuit protection, and the switch comprises a switch box, installation blocks are fixedly installed at the left and right ends of the interior of the bottom side of the switch box, spring mechanisms are fixedly installed at the left ends of the installation blocks, and connecting pieces are fixedly connected to the left ends of the spring mechanisms. Pulleys are movably mounted on the upper side and the lower side of the connecting piece, a magnet is fixedly connectedto the left end of the connecting piece, a mounting groove is formed in the switch box, and a control switch is movably mounted in the mounting groove. When a circuit is short-circuited and two conductive springs form a power-on loop, resistance is very large, high heat is generated accordingly, bimetallic strips connected to the left ends and the right ends of the conductive springs deform afterbeing heated, and the conductive springs are driven to retract and pull a movable connecting rod to move downwards from a protruding state to a straight state; meanwhile, the lower electrode is disconnected from the copper sheet, so the effect of protecting the circuit safety is achieved.
Description
technical field [0001] The invention relates to the technical field of circuit protection, in particular to a ventilated circuit switch capable of circuit protection. Background technique [0002] With the improvement of power supply requirements in electric power engineering, the performance requirements for circuit protection switches are also getting higher and higher. It will lead to serious consequences such as damage to power equipment, system failure, expansion of the scope of the accident, and even large-scale power outages. [0003] And now there are all kinds of electrical devices, and the power consumption pressure will increase accordingly. Therefore, the safety performance of the circuit switch is relatively high, and at the peak of power consumption, the internal power of the control switch is too high, and it is easy to make all internal components. These components generate high temperature, which accelerates the loss of internal components, and when the cir...
