Description
Technical field
This utility model relates to resistive technologies field, is specifically related to a kind of high-power high stability resistor.
Background technology
Board-like resistor is mainly used in starting, braking, speed governing and the load etc. of elevator, crane, port machine, milling train, hoist engine, electromotor, converter etc., its requirement has higher resistance stability and higher power, in order to the above-mentioned work waiting equipment normal, stable of fast and accurate control.But, existing bar resistor device uses conventional, electric-resistance silk, the unstable properties such as one starting, braking, speed governing and load, causes wear and tear of machinery relatively big and affects normal work；Its two power is little, it is impossible to solve the many electric current of main equipment, Control of Voltage requirement, narrow application range；Its three substrates heat dispersion is poor, causes resistor entirety service wear to increase, and service life is shorter.
Therefore, based on the problems referred to above, this utility model provides a kind of high-power high stability resistor.
Utility model content
Utility model purpose: the purpose of this utility model provides a kind of high-power high stability resistor, solves that existing resistor power is big, starts and the shortcoming such as braking ability is unstable, heat dispersion difference, improve and control precision, extends resistor service life.
Technical scheme: a kind of high-power high stability resistor, including stripe board, strip groove, L-shaped clamp, heat radiation circular hole, the first semicircle ceramic wafer, the second semicircle ceramic wafer and resistance wrapping wire；Described strip groove and L-shaped clamp are arranged on stripe board two ends；Described heat radiation circular hole is arranged on inside stripe board；Described first semicircle ceramic wafer, the second semicircle ceramic wafer are arranged on stripe board both sides；In described resistance wrapping wire uniform winding and stripe board；Wherein, resistance wrapping wire is constantan or nichrome wire.
The technical program, described stripe board, strip groove, L-shaped clamp and heat radiation circular hole use ferrum one-body molded prepared, and a length of 300mm, width are 100mm.
The technical program, the described first semicircle ceramic wafer, the second semicircle ceramic wafer use high-temp resisting high-humidity resisting, radioprotective electronic ceramics.
Compared with prior art, having the beneficial effects that of a kind of high-power high stability resistor of the present utility model: 1, use and circular louvre is set in ferrum stripe board, heat produced when working can be shed by time, and then ensures the control that resistor is accurate, stable；2, semicircle ceramic wafer has good insulating properties, it is ensured that non-interference between resistance wire；3, can flexibly with the use of, safe and reliable.Simultaneously this utility model simple in construction, production cost is low, easily promote.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high-power high stability resistor of the present utility model；
Wherein in figure, sequence number is as follows: 1-stripe board, 2-strip groove, 3-L-shaped clamp, 4-heat radiation circular hole, the semicircle ceramic wafer of 5-first, 6-second semicircle ceramic wafer, 7-resistance wrapping wire.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model.
One high-power high stability resistor as shown in Figure 1, including stripe board 1, strip groove 2,
L-shaped clamp 3, the semicircle ceramic wafer of heat radiation circular hole 4, first 5, second semicircle ceramic wafer 6 and resistance wrapping wire 7；Strip groove 2 and L-shaped clamp 3 are arranged on stripe board 1 two ends；It is internal that heat radiation circular hole 4 is arranged on stripe board 1；The first semicircle semicircle ceramic wafer 6 of ceramic wafer 5, second is arranged on stripe board 1 both sides；In resistance wrapping wire 7 uniform winding and stripe board 1；Wherein, resistance wrapping wire 7 is constantan or nichrome wire；Described stripe board 1, strip groove 2, L-shaped clamp 3 and heat radiation circular hole 4 use ferrum one-body molded prepared, and a length of 300mm, width are 100mm；The first semicircle semicircle ceramic wafer 6 of ceramic wafer 5, second uses high-temp resisting high-humidity resisting, radioprotective electronic ceramics, dielectric constant width changes in relative broad range, dielectric loss angle tangent is little, temperature coefficient of capacitance adjustable (or rate of change of capacitance adjustable), dielectric strength and insulating resistance value are high and ageing properties is excellent.
Wherein, during installation, resistance wrapping wire 7 is wound on the first semicircle ceramic wafer 5 and the second semicircle ceramic wafer 6 by groove, after extraction, connects the joint at two ends；Utilize and be fixed by strip groove 2 and the L-shaped clamp 3 at stripe board 1 two ends to during equipment, the heat diffusion that the circular hole 4 that dispels the heat during work will be distributed in time.This simple in construction, can flexible assembling use, resistance wire precision high, and then extend whole service life；This resistor power is high, applied widely simultaneously, and power is 350w-500w, Standard resistance range 0.1 Ω-500 Ω, is usable in the equipment such as elevator, crane, port machine, milling train, hoist engine, electromotor, converter, illumination.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvement, these improvement also should be regarded as protection domain of the present utility model.
