The technical scheme of the utility model embodiment is explained with reference to the accompanying drawing of the utility model embodiment and
Illustrate, but following embodiments only preferred embodiment of the present utility model, and not all.Embodiment in based on embodiment,
Those skilled in the art's obtained other embodiment on the premise of creative work is not made, belongs to of the present utility model
Protection domain.
Embodiment 1.
Referring to Fig. 1, the automatic release device with the air gap lightning protection device, including promoting the push rod of lightning protection device MOA
21st, support 3, the electromagnet 2 on the support and monitoring unit 1, the monitoring unit 1 gather the lightning protection device MOA
Ground wire by electric current, when the lightning protection device MOA is damaged, the monitoring unit 1 is generated by electric current according to described
Drive signal, the electromagnet 2 receive the drive signal and drive 21 action of the push rod.
What Fig. 2 showed monitoring unit 1 implements circuit, and the circuit is mainly by current acquisition and processing unit 10, letter
Number produce and to constitute with 12 3 parts of drive circuit unit of latch units 11 and electromagnet 2.Current acquisition and processing unit
By the ground wire of collection band gap lightning protection device MOA by electric current and through current in resistance property separating treatment acquisition current in resistance property,
The current in resistance property increase when lightning protection device MOA is deteriorated, when electric current increases to certain value, i.e. lightning protection device MOA is deteriorated to failure
When, by electric current is filtered and voltage stabilizing after produce and be enough to the signal for driving rear class signal to produce with latch units 11, rear class signal
Produce prime signal is latched with latch units 11 under prime current acquisition with the driving of 10 signal of processing unit and generate driving letter
Number drive rear class electromagnet drive circuit unit 12, to control 2 action of electromagnet.
Shown in Fig. 2, the operating voltage of each circuit unit of this monitoring unit 1 is by the storage in current acquisition and processing unit 10
Energy electric capacity 102 is provided.When there is lightning current to pass through, storage capacitor 102 stores part electric energy and uses for the unit of circuit.
Shown in Fig. 2, the current acquisition of this monitoring unit 1 is main with processing unit 10 by through lightning protection device MOA lower ends ground connection
The collection of current sensor 101 of downlead collection signal passes through electric current.By the storage capacitor 102 in parallel with current sensor and
Filter capacitor Transient Suppression Diode 103 in parallel and rectifier bridge 104 constitute resistive current separation circuit.Rectifier bridge 104 is defeated
Go out end to be connected with 105 two ends of filter capacitor, composition energy storage and filter circuit, 105 two ends shunt regulator diode 106 of electric capacity, with
105 both end voltage of clamp-on filtering electric capacity, there is provided the drive signal of late-class circuit simultaneously protects late-class circuit.
Shown in Fig. 2, the signal of this monitoring unit 1 produce the optocoupler 111 and 112 that has two same models with latch units 11 with
And reset switch 113 is constituted, for latching prime current acquisition with 10 output signal of processing unit and producing driving rear class electromagnetism
The drive signal of the drive circuit unit 12 of iron.When prime current acquisition has output signal with processing unit 10, optocoupler 111 is led
Logical, the optocoupler 111 of conducting drives optocoupler 112 to turn on, and 112 optocoupler output signals of conducting drive optocoupler 111 to turn on again, and such two
Interlocking is formed between individual optocoupler.Now, the output signal optocoupler when prime current acquisition is disappeared with 10 output signal of processing unit
Output signal is still effective, it is to avoid the signal pulse time is short, and electromagnet action time delay causes lightning protection device MOA reliably can not thread off
Problem, electromagnet automatically resets after the electric quantity consumption of energy storage filter capacitor is complete, makes lightning protection device MOA in self gravitation effect,
Lower Automatic-falling.
Shown in Fig. 2, in the utility model, the drive circuit unit 12 of 1 electromagnet of monitoring unit is by biasing resistor 121 and MOS

11 when having output signal, and metal-oxide-semiconductor 122 is turned on, and electric current controls electromagnet action by the coil 20 that metal-oxide-semiconductor flows into electromagnet 2.When
When the generation of prime signal and latch units 11 are without output signal, metal-oxide-semiconductor is not turned on, 20 kinds of no currents of coil of electromagnet 2, electricity
Magnet is in relaxed state.
Fig. 3 is to show to install fixed supporting structure schematic diagram.Support 3 is the installation base of whole automatic release device
Plinth, is provided with four the first connecting holes 31 on the downside of which, this four the first connecting holes 31 are relative with the installation fixing hole on electromagnet 2
Should, electromagnet is fixed on this four holes with four screws during installation；The downside of support 3 is additionally provided with four the second connecting holes
32, this four the second connecting holes 32 are corresponding with the installation fixing hole on monitoring unit 1, with bolt by monitoring unit 1 during installation
The bearer bar bottom surface of support 3 is fixed on, by taking the measure of blocking to avoid rainwater direct at frame door before and after bearer bar after installing
Shower monitoring unit 1；Meanwhile, the upside of support 3 also is provided with two holes 30 that are connected, and this hole that is connected is lightning protection device
MOA and the mounting interface of trip gear, lightning protection device MOA is by be connected hole bolt and the whole automatic release device phase
Even supported with providing the fixed of whole trip gear.Lightning protection device MOAMOA and automatic release device are all installed on installation draw-in groove
Interior.Automatic release device is on the downside of lightning protection device MOA.
Operation principle is as follows：When there is thunderbolt to occur, the electric energy of the storage part thunder and lightning of storage capacitor 102 provides whole circuit
Electric energy needed for work；If lightning protection device MOA is functional, the ground wire of lightning protection device MOA by electric current through current acquisition
With the current in resistance property very little obtained after processing unit 10, it is not enough to drive late-class circuit, therefore metal-oxide-semiconductor 122 is not turned on, electromagnet
No current in 2 coil 20, electromagnet are in relaxed state, and push rod 21 makes lightning protection device to lightning protection device MOA without active force
MOA is in the state of working online；If lightning protection device MOA performances deterioration occur and can not be further continued for being on active service, passed through by electric current
Current in resistance property after current acquisition and processing unit 10 is larger to produce the signal that be enough to drive optocoupler 111, then signal produce with
The metal-oxide-semiconductor 122 of the drive circuit unit 12 of the signal latch DM is turned on by latch units 11, now, electromagnet 2
Coil 20 in have electric current to flow through, produce magnetic field, the push rod 21 of magnetic field force DM 2 moved upwards, the pressure of push rod 21
Act on the lower end of lightning protection device MOA and promote lightning protection device MOA bodies to move upwards, lightning protection device MOA is made from installation draw-in groove
In exit, after the electric quantity consumption in storage capacitor 102 is complete, electromagnet 2 automatically resets, and push rod 21 is removed to lightning protection device MOA
Active force, lightning protection device MOA exits installation and draw-in groove comes off.
