Title:
BOX CORE MODULE, PLUG MODULE AND SURGE PROTECTIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/037163
Kind Code:
A1
Abstract:
A box core module, a plug module and a surge protective device. A plug module (8) comprises: a housing (2); bottom plates (4a, 4b); a plurality of box core modules (1) having independent tripping mechanisms; a first pin electrode; and a second pin electrode, wherein the plurality of box core modules (1) are vertically arranged on one side of the bottom plates (4a, 4b) in a side-by-side or opposite manner; the plurality of box core modules (1) are connected by means of internal connection electrodes so as to form a series and/or parallel combined circuit, and the combined circuit is led out by means of the first pin electrode or the second pin electrode. The plug module (8) is combined with a base (9). A modularized multi-form assembly-type surge protective device is provided. By means of different combinations of series connections and parallel connections of all the box core modules, the aim of completing mutual conversion between a high working voltage of the surge protective device and a large lightning strike through-current is achieved under the conditions of the same voltage-limiting element being used and the overall tripping means being unchanged.
