The closing of fruit switch button 301 then shows that earth protective device can run well, and can come into operation after test, corresponding in use
Indicator light include running indicator, voltage lamp, electric leakage lamp, shorted lamp and output lamp, each lamp lights the situation of then indication circuit,
However in short circuit electric leakage or circuit will take corresponding counter-measure under the action of by extraneous thunder and lightning, wherein when short circuit such as
Fruit electric current is more than original maximum rated current that the setting of valve 305 is set by overcurrent, the switch button 301 on earth leakage circuit-breaker
Disconnecting circuit and will show short circuit tripping times on display screen 304 in 0.1 second, to guarantee the safety of equipment, when
When the electric leakage that 15 arrive 30mA occurs for route, switch button 301 on earth leakage circuit-breaker will in 0.1 second disconnecting circuit and aobvious
Leakage tripping number is shown on display screen curtain 304, however thunder and lightning will be guided by lightning protection device 104 to big when lightning impulse occurs
Ground, so that equipment is protected not damaged by thunder and lightning, wherein connection having air switch 103, its working principle is that working as route
When generality overload, though overload current cannot be such that magnetictrip acts, thermal element can be made to generate certain heat, promote double gold
Category piece, which is heated, to be bent upwards, and is pushed lever to make to have contact with and is latched disengagement, main contact disjunction is cut off the power, when route generation is short
When road or heavy overload electric current, short circuit current is more than instantaneous trip setting current value, and magnetictrip generates sufficiently large suction,
Armature is attracted to and is hit lever, make to have contact with rotate axle bed be rotated up with lock disengage, latch under the action of reaction spring
By three secondary main contact disjunctions, to cut off the power, so that play the role of protecting circuit, the wherein model of air switch 103
IC65N, however in the serious place of a few thing dust in use, slide rail can be made by sliding recess 5 in using
403 slidings, so as to which shield 4 to be covered on to the surface of crust of the device 1, play the role of preferable proofing dust and protecting and prevent water
It penetrates into, and internal control structure and display screen 304 can be viewed through diaphragm of fenestration 402 when in use, do not influence it
Using the operation with button, so that protective value is preferable.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
