Embodiment Construction

[0018] A protective switch of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] like figure 1 , figure 2 , image 3 , Figure 4 as shown in figure 1 Among them, a and b are the structural diagrams of the protection switch, respectively. figure 1 There is an outer cover in a, figure 1 There is no outer cover in b. figure 2 a, b, and c are the schematic diagrams of different angles where the transformer is placed, Figure 4 a and b are schematic diagrams of another arrangement of transformers at different angles. The protective switch of this embodiment includes a housing 1 and a transformer. The transformer includes a middle transformer 3 and two side transformers 4 located on both sides of the middle transformer 3. The shafts of the two side transformers 4 are The centers are all perpendicular to the axis of the middle transformer 3, and a block 5 is provided between the two side transformers 4 to block them...

Abstract

The invention provides a protection switch which comprises a shell and mutual inductors, wherein the mutual inductors comprise one middle mutual inductor and two side mutual inductors positioned on two sides of the middle mutual inductor; the axes of the two side mutual inductors are vertical to the axis of the middle mutual inductor; a baffle plate for separating the two side mutual inductors is arranged between the two side mutual inductors; and the middle mutual inductor and the side mutual inductors are hollow mutual inductors. According to the protection switch provided by the invention, the mutual inductors are hollow mutual inductors, the axes of every two adjacent mutual inductors are vertical to each other, the hollow mutual inductors are good in linearity, and the mutual interference between the adjacent hollow mutual inductors is minimized.

Description

technical field [0001] The invention relates to a switch, in particular to a control and protection switch. Background technique [0002] Control and protection switch electrical appliances, the English abbreviation is CPS. It is the best substitute for low-voltage electrical appliances such as circuit breakers, contactors, thermal relays, and fuses. [0003] The control and protection switch products adopt a modular single product structure type, integrating the main functions of traditional circuit breakers (fuse), contactors, overload (or overcurrent, phase failure) protection relays, starters, isolators, etc. It has the functions of remote automatic control and local direct manual control, panel indication and electromechanical signal alarm function, overvoltage and undervoltage protection function, phase failure and phase loss protection function, and coordinated time-current protection characteristics (with reverse Time limit, definite time limit and instantane...
