Anti-explosion electric cable clip has two at least, and anti-explosion cable is located on flameproof enclosure, and anti-explosion electric cable clip is that middle part is through tubular, the through hole of anti-explosion electric cable clip and the inner chamber of flameproof enclosure through, seal between anti-explosion electric cable clip and flameproof enclosure;
Multipoint earthing terminal connects the earth by wire.
The integrated explosion proof system Surge Protector that described employing is protected by flameproof enclosure; it is characterized in that: the two ends of connector connect one end of fuse and one end of Surge Protector respectively by fusion; make one end of connector and fuse, connector all becomes to be integrated with one end of Surge Protector on electrically, the electrical contact area at connector two ends is not less than 2.5mm
2, the diameter of connector cross section is not less than 1.8mm; The resistivity of connector is not more than 2.4 × 10
-8Ω m, can select the metals like gold of high conductivity, silver or copper to become, connect in order to alternative wire, avoids the drawback adopting wire to connect the Up value increasing Surge Protector, and adopt wire to connect at present, wire longer Up value is higher, thus produces potential safety hazard.
The integrated explosion proof system Surge Protector that described employing is protected by flameproof enclosure, is characterized in that: multipoint earthing terminal comprises the earth terminal of at least individual mutual electrical connection, and described earth terminal is all electrically connected the earth; Multipoint earthing terminal replaces ground connection PE wire, and greatly strengthen the discharge capacity of Surge Protector, do not produce earth connection residual voltage, better protective circuit, reliability is higher.
The integrated explosion proof system Surge Protector that described employing is protected by flameproof enclosure, is characterized in that: Surge Protector selects voltage switch type, votage limit type or combined;
Voltage switch type: present high impedance when not having instantaneous overvoltage, once response thunder and lightning instantaneous overvoltage, its impedance just sports Low ESR, allows lightning current to pass through, is also referred to as " short switch type ";
Votage limit type: when not having instantaneous overvoltage is high impedance, but with the increase of surge current and voltage, its impedance can constantly reduce, and its current-voltage characteristic is strongly non-linear, sometimes referred to as " pincers die mould ";
Combined: combined by voltage switch type assembly and votage limit type assembly, can be shown as the characteristic that voltage switch type or votage limit type or both have concurrently, this is decided by alive characteristic.
When the utility model uses; wire penetrates flameproof enclosure respectively by anti-explosion electric cable clip; wire is made to connect fuse and multipoint earthing terminal respectively; being connected on by the utility model needs in protective circuit; when there being overpotential surge to produce; overpotential is released to greatly by Surge Protector action, makes circuit from infringement.
The beneficial effects of the utility model are: structure is simple, easy to use, thoroughly isolated, safe and reliable.
