Abstract
The utility model discloses a ten-thousand time safety tube, belonging to the technical field of electric appliance protection. The utility model is composed of a safety tube body, moving and static contacts, bimetallic sheets, reeds, a piece of armature, a piece of electromagnet, and electric current coils. The utility model is suitable for protection in terms of electric quantity limitation, over current, over load, short circuit, etc. When a circuit has faults, the utility model can automatically and effectively protect electric appliances and lines. The utility model has the advantages of no maintenance requirement, repeatable use, and simple structure. The utility model sends out different mixed audio signals to manipulate the corresponding movements of a relay which is arranged on a receiver, and therefore, the goal of controlling the power supply switches of different electric devices is obtained. In addition, remote control can be carried out on the switches of various electrical devices through a simple telephone interface.
Description
The utility model belongs to a kind of reusable, No. maintenance free ten thousand protective tubes of electric prospection technical field.
At present a lot of to the protection device of electrical equipment, circuit.As fuse, current relay, thermal relay, be individual devices, function singleness, complex structure, inconvenience is installed, maintenance capacity is big, what have can only use once, waste is big.
The purpose of this utility model provide a kind of not only simple but also can the brownout load, integrate No. ten thousand protective tubes of kinds of protect such as overcurrent, overload, short circuit, after fault is got rid of, but automatic recovery of power supply itself need not keep in repair, reusable.
The purpose of this utility model is achieved in that by insurance body, two ends and is fixed with and patches electrode, is made up of sound contact, bimetal leaf, electromagnet and current coil in the body.When electric appliance circuits surpasses the rated current of restriction or fault overcurrent, overload, electric current increases shrinks the bimetal leaf heating, its sound contact automatic disconnection, when short circuit appearred in circuit, electric current heightened, and current coil makes electromagnet produce magnetic force, attract armature to make the rapid disjunction in sound contact, cut off electric current, get rid of up to fault, circuit recloses automatically.
Owing to adopt such scheme, when circuit breaks down, can effectively protect electrical equipment and circuit automatically, self need not keep in repair, and is reusable, simple in structure, safe ready.
Further specify below in conjunction with the utility model accompanying drawing.
Among the figure: the end by insulation insurance body (3) patches electrode (1), (2), has fixed contact (4), moving contact (5), bimetal leaf (6), tie point (7), armature (10), reed (8), fixed connection point (9), electromagnet (11), current coil (12) to be connected on the plug-in electrode (13), (14) of body (3) other end in the body.
Claims (2)
1, No. a kind of ten thousand protective tubes, the insulation body that is had electrode by two ends is formed, and it is characterized in that: current coil, electromagnet, armature, reed, two temperature sheet metal and moving contact, fixed contact are arranged in the body.
2, No. according to claim 1 ten thousand protective tubes is characterized in that: the body two ends are fixed with and connect, intercalative electrode.
