Description
Technical field
This utility model relates to field of electrical equipment, is specifically related to one and falls stove formula spark gap.
Background technology
In medium voltage distribution network, annual thunderbolt causes the ratio of line tripping and device damage to be up to more than 70%, reduce
Lightning fault, improves power supply reliability, and installing thunder resisting equipment on distribution line is one of major measure, the most most widely used
Equipment is metal oxide arrester.
The thunder resisting equipment used in medium voltage distribution network mainly uses gapless metal-oxide lighting arrester, protects outside it
Set uses softness to have resilient silicone rubber, and explosion-proof performance is good, lightweight.Along with constantly changing of metal oxide arrester product
Good optimization, the pattern of metal oxide arrester also gets more and more.Gapless metal-oxide lighting arrester divides from functional structure
Mainly there is plain edition, fall type, band release unit type.Only keep away having understood various metal-oxide as distribution run unit
On the basis of thunder device performance characteristics, just can choose suitable spark gap and be installed in middle voltage distribution networks, could effectively reduce keeping away
The O&M cost of thunder device, it is ensured that systems stay is powered, improves power supply reliability.
Commonly use disconnector at present to realize spark gap function of automatic separating fault when breaking down or damage.De-
It is a kind of attachment device of spark gap from device, is generally used in series with spark gap.When spark gap is properly functioning, bear various machine
Tool power, electric power；By transient current, release overvoltage energy time, disconnector will not action.When spark gap is faulty or damages
Time, the thermal energy of power frequency fault current when disconnector utilizes spark gap to destroy and rapidly action, the high pressure being connected with spark gap
Line and earth lead disconnect, and make spark gap out of service.And have and significantly disconnect mark, it is simple to find rapidly trouble point.
Disconnector divides hot melten type and heat explosion type by operating principle, and wherein hot melten type is to cause body with surge arrester failure electric current
Or the temperature rise conduction of heat of additional heating element is to disconnector action, is mostly integral type, due to reasons such as design, techniques, tripping,
Malfunction happens occasionally.Heat-explosion type disconnector structural principle is: be connected in parallel with a capacitor device on discharging gap, and thermal explosion pipe is placed on to be put
In the bottom electrode in electricity gap.When spark gap normally works, the pressure drop on the capacitor of thunder and lightning and switching impulse current is the most not enough
So that discharging gap disruptive discharge, disconnector is failure to actuate；And when surge arrester failure damages, power frequency fault current is on the capacitor
Pressure drop then make discharging gap disruptive discharge and electric arc continuous heating thermal explosion pipe, the disconnector when thermal explosion pipe is warming up to about 400 DEG C
Action.The capacitor in parallel that novel heat-explosion type disconnector employing conductive silicon rubber is made, on discharging gap, is spark gap
Leakage current passage, is an off again the pyrotoxin of action under device little power frequency fault current, so that disconnector structural principle more closes
Reason, runs more reliable, is suitable for mutually with the feature of China electrical network and matches with the fault damage mechanism of metal oxide arrester.
Disconnector is used in series with spark gap, and its technical performance should meet: (1) regular service conditions should be used in series
Spark gap is identical；(2) should have the resistance characteristics identical with spark gap；(3) should have good action ampere-time characteristic, be suitable for me
The feature of state's electrical network and the fault damage mechanism with metal oxide arrester match；(4) should there is suitable mechanical strength.
