The invention belongs to the technical field of surge protection devices, and particularly relates to a combined low-voltage surge protection device which comprises a shell, a shell cover is hinged to the front face of the shell, a base body is fixed between the inner walls of the two sides of the shell, and protection module single bodies are inserted into grooves formed in the base body at equal intervals. And the protection module monomers are electrically connected with the base body. By arranging the shell, the first spring, the clamping plate, the clamping rod, the connecting rod, the connecting plate, the vertical rod, the pressing plate and the convex frame, when the base is spliced with the protection module single bodies and the protection module single bodies are fixed, the stability can be more stable, meanwhile, when the protection module single bodies are damaged and need to be detached from the base for replacement, the protection module single bodies can be more convenient to replace, and the working efficiency is improved. When the circuit is connected and the temperature in the housing is high, the heat dissipation assembly is arranged to help the heat dissipation of the interior of the housing, thereby guaranteeing the normal operation of the surge protection device.
Description
technical field [0001] The invention relates to the technical field of surge protectors, in particular to a combined low-voltage surge protector. Background technique [0002] Surge protector is commonly known as "lightning arrester" or "overvoltage protector". It is an indispensable protection device in equipment lightning protection. voltage, the surge protector can be turned on and shunted in a very short time, thereby avoiding damage to other equipment in the circuit by the surge. Most of the combined surge protectors currently used are composed of a base and multiple protection devices. The modules are spliced together, but when the current surge protector base is spliced and fixed with the protection module, the fixing performance of the base is poor, which easily leads to unstable electrical connection between the base and the protection module, and at the same time When the protection module is damaged and needs to be replaced, it is inconvenient to remove it fr...
