Disconnector, as lightning-arrest auxiliary products, is used in series with spark gap.Can action take off when surge arrester failure damages
From, it is to avoid fault spread, so that it is guaranteed that the safety of electrical network, reliability service, provide for fault spark gap simultaneously and substantially identify, be easy to
Maintainer finds trouble point in time and launches service work.Disconnector is divided into by use principle and performance：Hot melten type disconnector
And heat-explosion type disconnector, hot melten type disconnector using the power frequency short circuit current flowing through in inefficacy spark gap, make in disconnector contain gold
Fuse piece fuses and to reach disengaging purpose.Heat-explosion type disconnector is in disconnector using the power frequency short circuit current flowing through during inefficacy is taken shelter from the thunder
Middle generation electric arc, ignites thermal explosion element to reach disengaging purpose.
Spark gap adds band disconnector, can avoid the expansion of accident, improves the operational reliability of electrical network.But spark gap adds band
Disconnector, also increases a weak link while improving system operation；The shell of disconnector itself relatively more fragile it is desirable to
All should ensure that during manufacturing, transport and using and handle with care, be otherwise vulnerable to external force and damage, then after coming into operation
Occur can not be operating normally during spark gap accident, or spark gap does not break down, disconnector misoperation.So, spark gap installs additional
Disconnector there is also certain risk, and this is accomplished by a kind of dependable performance ground disconnector and is connected on safe handling on spark gap, protects
Card system equipment normal reliable is run.
Content of the invention
For solving above-mentioned technical problem, this utility model provides a kind of lightning arrester with thermal-explosion type disengaging device, spark gap
After damage, disconnector action first, earth lead falls, and fault spark gap has obvious mark, is easy to search fault.Lose absolutely
The spark gap of edge performance is supported and insulated by insulator support, and system can normally be run.
This utility model be employed technical scheme comprise that：
A kind of lightning arrester with thermal-explosion type disengaging device, including thermal-explosion type disengaging device, spark gap, thermal-explosion type disengaging device de-
Connect spark gap from device housing upper end, embedded between spark gap and disconnector housing be connected insulating support, upper clamping nut, push
Tight nut is connected on the binding post of thermal-explosion type disengaging device, crimps earth lead one between upper clamping nut and lower clamping nut
End, the earth lead other end accesses grounded screen.It is provided with the disconnector housing of thermal-explosion type disengaging device between nonlinear resistor, electric discharge
Gap, hot air puffer, described nonlinear resistor, discharging gap are connected in parallel, are connected with hot air puffer afterwards.
Spark gap is connected in series with thermal-explosion type disengaging device, and junction embeds and connects insulating support one end, and insulating support is another
End is fixed on tower bar.
A kind of lightning arrester with thermal-explosion type disengaging device of this utility model, technique effect is as follows：
1：Separator for lightning arrester adopts thermal explosion principle, and after spark gap breaks down, power frequency Leakage Current increases, and works as electric leakage
Discharging gap electric discharge when stream increases to certain value, in disconnector.Gap discharge causes the micro gunpowder explosion in disconnector, takes off
Blow from device shell, so that spark gap is disengaged with high-pressure system.Prevent the blast of spark gap, it is to avoid the generation of accident.Its performance
Meet the technical requirements in GB11032-2000.2：Band thermal-explosion type disengaging device is mainly used in 10kV and following power system,
Can be used for, in 35kV system, being arranged between the bottom of spark gap and ground wire, spark gap is arranged on insulating support.3：Spark gap
After damage, disconnector action first, earth lead falls, and fault spark gap has obvious mark, is easy to search fault.Lose absolutely
The spark gap of edge performance is supported and insulated by insulator support, and system can normally be run.
Brief description
Fig. 1 is the structural representation of this utility model lightning arrester.
Fig. 2 is the thermal-explosion type disengaging device structural representation of this utility model lightning arrester.
Specific embodiment
As shown in Figure 1 and Figure 2, a kind of lightning arrester with thermal-explosion type disengaging device, including thermal-explosion type disengaging device, spark gap 7,
Disconnector housing 1 upper end of thermal-explosion type disengaging device connects spark gap 7, embedded between spark gap 7 and disconnector housing 1
Connect insulating support 6, upper clamping nut 2, lower clamping nut 3 are connected on the binding post 4 of thermal-explosion type disengaging device, upper compression
Earth lead 5 one end is crimped, earth lead 5 other end accesses grounded screen between nut 2 and lower clamping nut 3.
It is provided with nonlinear resistor 10, discharging gap 9, hot air puffer 8 in the disconnector housing 1 of thermal-explosion type disengaging device, described
Nonlinear resistor 10, discharging gap 9 are connected in parallel, are connected with hot air puffer 8 afterwards.
Spark gap 7 and thermal-explosion type disengaging device are connected in series, and junction embeds and connects insulating support 6 one end, and insulating support 6 is another
One end is fixed on tower bar.
When spark gap 7 breaks down short circuit, voltage directly will be passed to thermal-explosion type by spark gap 7 and take off by system voltage
In device, under action of high voltage, discharging gap 9 electric discharge causes nonlinear resistor 10 resistance to decline, electric current increases, and causes heat
The heating blast of quick-fried device 8, make earth lead 5 disengage with spark gap 7, it is to avoid system earth is short-circuit and accidents caused.
Thermal-explosion type disengaging device is a kind of adnexa of spark gap 7, is used in series with spark gap 7.Its objective is to go out when spark gap 7
During existing abnormal failure, using the power frequency short circuit current flowing through in spark gap 7 by disconnector action, make the earth terminal of disconnector automatic
Disengage, spark gap 7 logs off operation, and Accident prevention expands further, and provides fault spark gap with the disengaging mark of observability
Know, be easy to attendant and find that trouble point is safeguarded and changed in time.
When spark gap 7 is in normal work, disconnector assumes exchange conducting state and does not affect the former working condition of system
And the protection feature of spark gap, it is ensured that the normal operation of system, makes spark gap be really achieved non-maintaining use requirement.
