And it is this need increased trend year by year, using original circuit wiring pattern, i.e. poling mode, many is brought during construction
Difficulty, moreover, when distribution system to be changed, making it become simple, some are nearly impossible, if however, using bus
If groove, it is very easy to just achieve the goal, also building can be made to become more attractive in appearance in addition.
Bus duct fully demonstrates its superiority when high current is conveyed compared with traditional cable, simultaneously because adopting
With new technology, new technology, contact resistance and the temperature rise of bus duct both ends junction and branching port splicing position are greatly reduced,
And high-quality insulating materials has been used in bus duct, so as to improve the security reliability of bus duct, make whole system more
Add kind.
Bus duct feature be with series matching, commercial production, small volume, capacity is big, the design and construction cycle is short, assembly and disassembly
Facilitate, will not burn, safe and reliable, service life it is long.
At present, the damage of bus duct is generally that long term overloading operation is caused, and bus duct overload mainly considers radiating,
When load current exceedes rated current, bus duct internal copper discharge heat, internal temperature rises.Because bus duct No-mistake Principle itself
Safeguard measure, usually long-play can make bus duct and its distribution line be in temperature rising state for a long time, therefore conductor connects
Point, terminal all can be lossy, and the insulating properties of circuit are also reduced, and accelerated ageing influences the service life of bus duct.If for a long time
Serious overburden operation, bus duct and its distribution line temperature are drastically raised, and line insulation softening is disintegrated, so that cause short circuit,
Lower end breaker is triggered a series of harm such as to burn, the life given people brings potential safety hazard, causes great property loss；Cause
This is particularly important to keeping electrical equipment normally to run there is provided a kind of bus duct joint apparatus for warning overload.
The content of the invention
Described above in order to overcome the shortcomings of, the purpose of this utility model is to provide a kind of bus duct joint overload-alarm dress
