Abstract
The utility model provides a clearance type one -level surge protector, whether main the solution has clearance type one -level surge protector installation back now, can't move with electricity by on -line monitoring surge protector to and unablely under the condition of electrified operation judge whether undamaged problem of surge protector. This clearance type one -level surge protector includes upper cover, lower cover and ignitor electrode, the space department of upper cover and ignitor electrode is provided with and is used for the monitoring system whether electrified and judge whether undamaged circuit board of surge protector.
Description
Technical field
The utility model is related to a kind of lightning protection device and in particular to a kind of clearance type one-level surge protector.
Background technology
Clearance type one-level surge protector is installed in low voltage incoming line cabinet, wind-powered electricity generation and photovoltaic system boosting case low pressure side,
For prevent atmospheric over-voltage and switching overvoltage to electrical equipment hurtful device.
There is problems with clearance type one-level surge protector in the market：
1st, surge protector whether charging operation cannot be monitored, during maintenance, easily operator is worked the mischief.
2nd, it is impossible to judge whether surge protector is intact in the case of charging operation.Can not find in time and change damage
Bad surge protector, is easily caused and is damaged by protection equipment.
Content of the invention
The utility model provides a kind of clearance type one-level surge protector, mainly solves existing clearance type one-level surge and protects
It is impossible to on-line monitoring surge protector whether charging operation after shield device is installed, and cannot judge in the case of charging operation
The whether intact problem of surge protector.
Particular technique solution of the present utility model is as follows：
This clearance type one-level surge protector includes lid, lower cover and ignitor, the sky of described upper lid and ignitor
At gap, it is provided with whether powered and judge the whether intact circuit board of surge protector for monitoring system.
Described circuit board includes resistance, diode and light emitting diode, after diode is in parallel with light emitting diode again with electricity
The fuse series connection of resistance and surge protector；Described light emitting diode is exposed to the outer side being formed by upper lid and lower cover.
The utility model has the advantage of：
This clearance type one-level surge protector, has monitoring system whether powered and judge whether surge protector is intact
Function, effectively increases the safety and reliability of product.
Brief description
Fig. 1 is the utility model circuit theory diagrams；
Fig. 2 is the utility model light emitting diode outline drawing；
Fig. 3 is structural representation；
Accompanying drawing is detailed as follows：
Cover on 1-；2- circuit board；3- circuit board link；4- ignitor；5- circuit board support；6- junction block；7- electricity
Pole support；8- lower cover；101- resistance；102- diode；103- light emitting diode.
Specific embodiment
As shown in Figure 3：Clearance type one-level surge protector includes lid, lower cover and ignitor, and wherein circuit board is installed
Gap between upper lid and ignitor, dismounts maintenance by electric iron.
Concrete structure can adopt：Circuit board is arranged on circuit board link, it is solid that circuit board link passes through screw
It is scheduled on circuit board support, circuit board support is fixed by screws on junction block, circuit board support shape and ignitor phase
It is adapted to and gap is set and ignitor between, ignitor is fixed on electrode suppor.
As shown in Figure 1：Circuit board includes 1 resistance, 1 diode and 1 light emitting diode, wherein diode with luminous
Connect with the fuse of resistance and surge protector again after diodes in parallel, resistance is used for current limliting, diode is used for preventing luminous two
Pole pipe flashes, and light emitting diode primarily serves powered indicative function, first passes through bright light whether powered to judge surge protector
Run, if lamp is bright, proof system is powered.To judge whether surge protector intact secondly by bright light, light emitting diode with electricity
Fuse in surge protector is cascaded structure, and the bad then surge protector of fuse can not be lighted a fire by ignitor, gone out by lamp and sentence
Power-off surge protector damages.Thus whether reach monitoring system powered and judge the whether intact function of surge protector.
Claims (2)
1. a kind of clearance type one-level surge protector, including on lid, lower cover and ignitor it is characterised in that：Described upper lid and
Whether the gap between ignitor, be provided with powered and judge the whether intact electricity of surge protector for monitoring system
Road plate.
2. clearance type one-level surge protector according to claim 1 it is characterised in that：Described circuit board include resistance,
Diode and light emitting diode, diode is connected with the fuse of resistance and surge protector with after light emitting diode parallel connection again；Institute
State light emitting diode and be exposed to the outer side being formed by upper lid and lower cover.
