Description
Technical field
The present invention relates to the automatic alarm system of a kind of device for fusing, fuse failure, and automatic alarm can be monitored in real time.
Background technology
Atmosphere produces negative thundercloud during flowing, along with the accumulation of negative charge in negative thundercloud, its electric field intensity by
Cumulative add, when reaching to a certain degree, i.e. start ladder-type downwards and jump electric discharge, referred to as descending leader electric discharge.When under this
When row guide moves closer to ground object and reaches certain distance, ground object produces point discharge under highfield effect, and
Forming upward leader, and develop towards descending leader direction, both i.e. define lightning channel after joining, and are the formation of thunder therewith
Electricity.It is generally believed that when thunder and lightning descending leader develops downwards from thundercloud, its ladder-type jumps only to be affected by ambient atmosphere,
The target that neither one determines.Only when completing last ladder-type and jumping, it just must select one and be hit object.Cause
This, can install arrester on protected object, makes upward leader and descending leader join, to avoid thunderbolt.
Arrester is exactly the metal object being specifically used to accept thunder and lightning.The metallic rod connecing sudden strain of a muscle is referred to as discharging rod, connects the gold of sudden strain of a muscle
Belong to line and be referred to as lightning conducter, connect the metal tape of sudden strain of a muscle, wire netting is referred to as lighting proof strip, lightning conduction.Discharging rod exceeds protected object, again and greatly
Be joined directly together, when lightning leader close to time, between it and thundercloud, electric field intensity is maximum, thus can be inhaled by the passage of thundercloud discharge
Guide to discharging rod itself, and with grounding device, lightning current is released in the earth safely through downlead, make protected object body
From direct stroke.
Owing to outdoor transmission line of electricity generally sets up in high-altitude, easily become the object that hit of thunder and lightning, thus built on stilts defeated
Generally equipped with overlapping lightning arrester in electric line more.But, after lightning arrester damages, lightning-arrest effect can be lost, as can not be timely
Find the lightning arrester of fault, easily make circuit be struck by lightning, cause large-area power-cuts.
Outdoor transmission line of electricity is usually installed with fuse.Fuse refers to when electric current exceedes setting, produces with itself

In prior art, it is utilized in the sidewall opening of electrical equipment more, extraneous cooler air is introduced or by casing for electric appliances
The mode that interior relatively warm air is discharged cools down, or housing entirety is cooled down so that be heated at electronic component
Gas is met cold after touching housing, passed by heat, is back at electronic component after cooling again.In this type of cooling, need
The system of factor to be cooled is put in the position that gas flowing in housing to carry out integral arrangement, even electronic component
About.And, it is important to, to adopt in this way, the temperature in housing cannot decrease too low, and cools down the gas of a lot of electronic component
Be into the heated gas of other electronic components, such as, with the gas of seventy or eighty degrees Celsius, go to cool down those temperature
Degree is 100 degrees Celsius, these elements must not be cooled to five or six ten degrees Celsius, so the operating temperature of electronic component
Also cannot significantly reduce.

Circle fixing body 21 also can drive valve plate 15 to be moved, and coil 17 is arranged in magnetic field, and the direction in magnetic field is represented by ⊙ in the drawings,
Magnetic field can be produced by U magnet, and magnetic field is for controlling valve core movement to change the openings of sizes of electrically operated valve, the magnetic in magnetic field
It is axial that sense line is perpendicular to coil, and the opening part of electrically operated valve is provided with the spring 23 being connected with valve plate 15, and spring 23 is set in cunning
On moving axis 14, sliding axle 14 is also fixing with valve plate 15 to be connected, and the other end of spring 23 is against and is fixedly mounted on cooling line 13
Spring support 19 on, spring 23 is for promoting valve plate 15 to close the opening of electrically operated valve, and electrically operated valve is arranged on cooling tube
On road 13, gas outlet 16 setting direction of electrically operated valve is so that the air-flow sprayed by opening sprays towards electronic component 22, cold
But pipeline 13 is positioned at second side of pcb board 2, and second is the reverse side of first, and cooling line 13 is defeated with cooling gas
Enter device or cooling gas generating unit connects.
Wherein the air inlet of cooling line 13 uses the mode from housing external admission, particularly, by cooling gas inlet
Device air inlet, through defecator 12, then has cooling fan 11 to be blown in cooling line 13.
When using gas produced by the cooling gas or cooling gas generating unit introduced from the external world, pass through pipeline
The electronic component 22 importing to heating is other, it is possible to use temperature lower, the most heated by other electronic component 22
These electronic components 22 are cooled down by cooling gas, and cooling effect is more preferable, and rate of cooling faster, is beneficial to realize electricity
The temperature of sub-element 22 maintains in lower level.And, by coil 17 being connected in series to circuit board in order to connect electronics unit
In the circuit of part 22, when electronic component 22 more needs to dispel the heat, and all thermal powers produced by it, derive from electrical power, and
Electrical power is the biggest, and its electric current is the biggest, so coil 17 can produce bigger active force, band moving winding fixing body 21 and valve
The plate 15 right side in figure is moved, to resist elastic force produced by spring 23.When bigger elastic force can be produced, its elastic shape
Becoming the biggest so that the opening of electrically operated valve is the biggest, the flow of the cooling gas that it can pass through is the biggest, and cooling capacity is more
By force.It is achieved thereby that the different cooling effects of the electronic component 22 for different operating temperature, or for same electronic component 22,
Different cooling effects when different temperatures, thus improve cooling gas input device or cooling gas generating unit exists
Import work efficiency during equal number cooling gas, improve cooling capacity.
It is understood that 1. the spring in Fig. 2 is spiral compression spring, this spring is used for promoting valve plate, so that drawing
QI KOU is closed, it is also possible to replacing with spiral stretching spring and torsionspring, those skilled in the art all can be according to the application's
Design is directly realized by these technical schemes without creative work；2. Fig. 2 uses by the way of air inlet, introduce cooling
With gas, liquid nitrogen actually can also be utilized to produce the nitrogen of cooling, it is achieved cooling, use the mode of liquid nitrogen to carry out cold
But, not only gas temperature is the lowest, and cooling capacity is strong, and the dust that will not produce in air cooling pollutes electronic component table
Face, the problem reducing electronic element radiating ability.
