Description
Technical field
The utility model relates to electric armour clamp technical equipment field, specifically a kind of parallel groove clamp.
Background technology
The safe handling of parallel groove clamp is directly connected to the reliability of city power distribution circuit, and the connection major part of current distribution line drainage thread and main line adopts parallel groove clamp.Through in a few years running discovery, there are scaling loss, line-broken malfunction to occur more, when large load operation in summer, because parallel groove clamp heating makes wire clamp and terminal scaling loss disconnect, cause line tripping and having a power failure, reducing circuit operational reliability.
For JB-3 type parallel groove clamp, the improper use of parallel groove clamp easily causes contact to generate heat, and supply line's reliability is reduced, is in particular in three aspects:
(1) JB-3 type parallel groove clamp, be applicable to from all wires within the scope of 120-150 square millimeter cross section from design concept, applied widely, a lot of convenience is brought to aspects such as engineering construction, material selection and buyings, but in actual moving process, workmen commonly uses parallel groove clamp and is connected gold utensil as backbone with drainage thread, and makes up the larger deficiency of wire diameter difference with aluminium armor tape.The rated current flowing through backbone but will be far longer than the rated current of drainage thread, when backbone is at large load operation, the connection JB-3 type parallel groove clamp of terminal and the contact area of wire but do not change, only maintain the level meeting low current and pass through, and the electric current suddenly increased is through this type of parallel groove clamp, because the corresponding increasing of excessive resistance causes heating, line fault is caused to take place frequently.
(2) while wire clamp heating, the conducting line segment be connected is scaling loss, distortion at high temperature, in turn increases the gap between wire clamp and wire, increases excessive resistance, causes wire clamp and wire again to generate heat, vicious circle, finally burn out broken string and cause the accident.
(3) contact area of wire clamp and wire is little, wire all can not be included in wire clamp, when constructing or overhaul, if crimping is firmly excessive, easily causing wire to damage, being partial to the side damage wires do not stressed.
In addition, owing to not arranging position limiting structure to bolt or nut, thus when fastening bolt fastening assembly, if screw in screw bolt and nut, another can together rotate thereupon, the great inconvenience to installment work band, if work high above the ground, danger also can increase.
