The junction box provided by the utility model can satisfy the special working condition that high current passes through the motor for a large-scale excavator during work. Meanwhile, the junction box can save installation space and materials, provide convenience for leading out cables, reduce work difficulty and improve work efficiency.
Description
Technical field
The utility model relates to big electric current power supply motor and electric equipment, relates in particular to terminal box, is specially a kind of terminal box that is applicable to low-voltage, high-current.
Background technology
The large-scale power shovel that uses in the present mining is because the particular surroundings of its work is abominable, operating condition is complicated, causes existing common terminal box not satisfy the operating condition requirement of large-scale power shovel motor.And along with power of motor strengthens, current of electric constantly increases, and originally does the requirement that lead-out wire has not reached current density by single threephase cable, therefore needs a kind of terminal box that is applicable to low-voltage, high-current of exploitation especially, so that satisfy abominable service conditions.
Existing common terminal box threephase cable connected mode is the tiling mode, volume is bigger, attached cable difficulty after the outlet, large-scale power shovel motor internal outlet cable size is big, be difficult for bending, use three homophase lead-out wire outlets from same hole of common terminal box, surface circulation heating problem caused energy loss when unit cable transmission of electricity that big electric current causes took place easily.
Summary of the invention
Existing common terminal box volume is big, wiring is difficult in order to solve for the utility model, be easy to generate the catabiotic problem of circulation heating phenomenon, and a kind of terminal box that is applicable to low-voltage, high-current is provided.
The utility model is concrete to adopt following technical scheme to realize: a kind of terminal box that is applicable to low-voltage, high-current, comprise that supporting seat and three-dimensional installation are used to be connected the three-phase copper bar of motor inside lead, supporting seat is fixed in terminal box box body inside, supporting seat is a ledge structure, be fixed with two copper bars respectively according to height on it, the 3rd copper bar is fixed in terminal box box body inside.
Utilize the three-phase copper bar to make lead-out wire, satisfy the big electric current of motor and pass through operating condition.Three-phase copper bar space multistory formula is installed, and makes things convenient for user installation inlet wire cable.And during long distance power transmission, U, V, the big cable of W three-phase be simultaneously from a hole outlet, the magnetic field of cancelling out each other, eliminated heating problem, can satisfy the long distance power transmission requirement, surface circulation heating phenomenon when reducing the transmission of electricity of homophase unit cable.The terminal box cover plate is taked seal approach, connects to adopt spring clip to connect, and makes things convenient for the user to dismantle.The terminal box box body can satisfy special environment conditions such as dust storm, high temperature, high and cold, plateau, humidity, salt fog.
Terminal box box body inside also comprises the combination junction block, adopts major-minor combination junction block, with explosion-proof blast switch, auxiliary switch, explosion-proof fan, electric heater, air pressure relay, tightly stop control assembly cable such as button by strong and weak electric current wiring.Terminal box box body inside is provided with dividing plate, dividing plate with heavy current and weak current separately, can prevent effectively that magnetic field that heavy current and weak current produce from interfering with each other influences control signal.
Compared with prior art, a kind of terminal box of low-voltage, high-current that is applicable to of providing of the utility model has following advantage:
(1) replace original lead-out wire with the three-phase copper bar, copper bar conducts electricity very well, and can satisfy passing through of big electric current in the large-scale power shovel machine operation, satisfies the special operation condition that large-scale power shovel motor uses.
(2) three-phase copper bar space multistory formula is arranged, is installed, and makes things convenient for user installation inlet wire cable.Three-phase copper bar spatial arrangement is installed, and guarantees enough arcing distances, can save installing space, save material, and can reduce difficulty of processing again; Simultaneously, the installation of arranging of three-phase copper bar space multistory formula is convenient to cable and is drawn, and reduces work difficulty, increases work efficiency.
