Description
Technical field
The invention patent relates to power distribution network arrester technical field, specially a kind of change gapless arrestyer protects mechanism
Combinational gap device and preparation method thereof.
Background technique
In long-term use, the main components varistor of Zinc-Oxide Arrester is held traditional zero-clearance zinc oxide lightning arrester
By operating voltage and different amplitudes, instantaneous lightning surge, the switching overvoltage of pulsewidth, electric property is easily deteriorated, and arrester is let out
Leakage current incrementally increases, and line loss is caused to improve, and is unfavorable for the economical operation of power grid, if arrester is breakdown, also will cause single-phase
Ground fault causes switch protection to act and have a power failure；Because surge arrester failure largely belongs to interior breakdown hidden failures, need to consume
A large amount of human and material resources search fault point, and extension restores electricity the time.
Existing Zinc-Oxide Arrester has two class of insulator arrester and silicon rubber arrester, and service performance respectively has superiority and inferiority.Insulator
Surge arrester failure point is easily found, ablation resistance is good, but ceramic seal is poor, also cumbersome, limited in cross arm of tower load
Situation should not be installed；Silicon rubber arrester is light-weight, easy for installation, and durability against pollution is strong, even if could be used that in salt fog place, especially
It is adapted to coastal area and the serious area of industrial pollution, but silicon rubber sealing material anti-aging property is unstable, in the temperature difference
The disadvantages of changing greatly or runing time be close to the life of product later period, causing its poor sealing.
On-line operation arrester parameter sampling observation, replacement etc. work require to carry out under power-off condition, with power supply can
By the raising of property index, the chance of grid power blackout and time are more and more nervous, make troubles to the dimension inspection work of arrester.
Patent of invention content
The present invention is intended to provide a kind of combinational gap device and preparation method thereof for changing gapless arrestyer protection mechanism,
By increasing by one section of discharging gap in arrester high-voltage end, which, which can ensure that, is effectively isolated system power-frequency voltage, prevents
Because route send the problem of not powering on caused by surge arrester failure, the operational reliability of system is improved.
In order to achieve the above object, the invention proposes technical solutions below:
A kind of combinational gap device changing gapless arrestyer protection mechanism, including a high-permitivity ceramics gap, the height
The ceramic gap of Jie is connect with the top of the gapless arrestyer, and a high-field electrode is radially drawn in the upper end of the high-permitivity ceramics,
The high-field electrode and the high tension terminal of described device connect, and an arrester, institute are radially drawn in the lower end of the high-permitivity ceramics
The low-field electrode for stating arrester and described device connects, and forms discharging gap between the high-field electrode and the arrester.
The high-field electrode is different from the length of the arrester, the end face of the two not in the same vertical plane, thus anti-
Gap is stopped and short circuit is bridged by sleet.
The high-field electrode is covered with the arrester exerteding metalwork by silicon rubber, to prevent because gapless is lightning-arrest
After device damage, gap is caused the ground fault being shorted by toy.
The high-field electrode passes through a L shape connector and high tension terminal, low-field electrode phase with the arrester respectively
Even.
The low-field electrode is a metallic conduction nut groove for being set to high-permitivity ceramics gap bottom.
The high-field electrode is a metallic conduction screw.
The top of the high-permitivity ceramics gap and the gapless arrestyer passes through screw connection, it can be achieved that charged for replacement,
The work such as arrester parameter detecting, disassembly gapless arrestyer ontology, do not influence normal power supply.
Meanwhile a kind of gap production method of change gapless arrestyer protection mechanism being provided, it is lightning-arrest in the gapless
The above-mentioned combinational gap device for changing gapless arrestyer protection mechanism of the top connection one of device.
Bring of the present invention the utility model has the advantages that
The present invention passes through between the top of gapless arrestyer setting one changes the combination that gapless arrestyer protects mechanism
Gap device, to increase one section of discharging gap, discharging gap size is predetermined according to distribution line voltage class, even if taking shelter from the thunder
The damage of device resistor disc, which may insure to be effectively isolated system power-frequency voltage, caused by preventing because of surge arrester failure
Route send the problem of not powering on, and improves the operational reliability of system.Meanwhile the device and arrester be by screw connection, when keeping away
Thunder device in the event of failure, can charged for replacement, detection, disassembly lightning arrester body, do not influence often to power.The device electric property is steady
Fixed, ablation resistance is good, simple with gapless arrestyer connection type, is able to achieve that high-permitivity ceramics gap is permanent, is recycled, drop
The operation cost of low line thunder protection.Combinational gap arrester part uses the technical parameter of gapless arrestyer, even if between electric discharge
Gap is short-circuited, and can still charge longtime running.The high-field electrode of device and the end face of arrester are non-coplanar after extending, therefore device
High and low pressure electrode in the same vertical plane, can not prevent gap from bridging short circuit by sleet.The combinational gap device is directly parallel in
On insulator steel cap, do not change original rod-type and insulator, it is easy for installation, construction cost can be substantially reduced and reduce O&M work
Make, and will not go offline, the failures such as single-phase earthing, does not influence normal power supply.Moreover, the use longevity of arrester valve piece can be extended
Life, is easy to search failure, the operation cost of arrester is effectively reduced, and has very high economy and society value.
