Description

technical field

[0001] The invention relates to the field of switches, in particular to a capacitance compensation switching switch. Background technique

[0002] Existing thyristor switches are of the exposed type, that is, both the thyristor components and the heat sink are exposed to the outside. Under such working conditions, these devices are easily subject to external interference and cause false triggering of the thyristor, and The protection performance is poor, and the operator is easy to touch during the installation and debugging process, causing personal safety accidents such as electric shock, so people consider adding a shell, but the installation of the shell and the heat dissipation base has problems such as unstable installation and lack of closeness; some The thyristor switch has a small terminal block or even no terminal block, which makes it very inconvenient for the operator to connect during installation and use. With a small terminal block, it is easy ...
