Fuse support piece (base) with DIN mobile guide rails

Abstract

The invention relates to a fuse support piece (base) with DIN mobile guide rails. The fuse support piece with the DIN mobile guide rails comprises two split fuse link connecting plates (contacts), two split fuse support piece base bodies and the DIN guide rails. The fuse link connecting plates (contacts) are fixed on the support piece base bodies through screws for screw holes in the two sides of the middle parts of the connecting plates (contacts). The support piece base bodies are arranged on the DIN mobile guide rails in a nesting mode and are fixed on the DIN mobile guide rails by screws through screw holes in the lower portions of the support piece base bodies, so that the fuse support piece (base) with the DIN mobile guide rails is formed. The fuse support piece with the DIN mobile guide rails has the advantages that the defect that fuse links and fuse support pieces in an existing fuse product are all designed to be in one-to-one arrangement, so that replacing and substituting are unavailable is overcome, one DIN mobile guide rail is additionally arranged to be mounted at the bottom of the fuse support piece, through the DIN mobile guide rails, the two split fuse support piece base bodies can be assembled to be in various mounting sizes, and therefore the applied range of the fuse support piece is expanded.

Description

Technical field: [0001] The invention relates to a low-voltage circuit power distribution system in the field of medium and low-voltage electrical appliances, a complete device power protection and control system, a semiconductor equipment protection system and a solar photovoltaic power generation system. It is mainly used in electrical installations as line overload and short circuit protection (gG / gL), short circuit protection of semiconductor equipment and its complete sets of devices (aR), motor short circuit protection (aM), and solar energy discovery system protection (gPV). Fuses are used. Background technique: [0002] At present, the fuse support (base) used to assemble the fuse in the distribution system of the medium and low voltage electrical appliances, whether it is a bolt connection method or a contact knife insertion method, is a fixed size, and the fuse and the support (base) ) fit is a one-to-one way, for example, the fuse of size 1 can only be equipped w...

Problems solved by technology

[0003] 1. The fuse body and the fuse support piece are equipped one-to-one, which are unique and irreplaceable in use. When the fuse support piece is damaged during actual use and must be replaced, if there is no spare, it will be impossible to Timely replacement of power distribution lines or electrical equipment cannot quickly restore power supply

[0004] 2. Because fuses and fuse supports are equipped one-to-one, product design, mold making, production equipment configuration, production and preparation of support parts must be carried out in a one-to-one manner, not only the workload Large, and the investment in materials and equipment is also large, resulting in the occupation of resources and the increase of product costs

Therefore, it not only causes the occupation and waste of resources, but also limits the expansion of the scope of application of fuse products and the continuous development of technical improvements.
