The device of shield is easy to use and safeguards.
According to the present invention, above-mentioned technical problem passes through the device solution according to claim 1.
Of the invention is significant the advantage is that realizing by the contact device that can mechanically drive from hull outside from manufacture ground
To the complete pre-assembled transport on installation ground.It even can just carry out the filling of protection gas before transportation when necessary, so that
Scene no longer needs any to be related to the operation of gas when installing on electric high-voltage facility.It can save and open safeguard cover plate to adjust
Trial assembly sets or separates resistor column and casing for upkeep operation.It can faster and more simply be installed with this, with section
Cost-saving.
In the preferred embodiment of the apparatus according to the invention, contact device has threaded rod, the threaded rod construction
For bear hull outside rotation and the mobile contact being connect with resistor column, wherein the contact can be towards or away from covering
Move to cooperation contact on pipe.Threaded rod is a kind of simple mechanical structure, for that will be converted into the axis along bar
Longitudinal movement；Therefore its is long-tested and can use at low cost.
In the other preferred embodiment of the apparatus according to the invention, there is height with the electric utility that dielectric insulate
Pressure transformer.This is favourable, because high-tension transformer generally has to be protected for objectionable overvoltage.
In the other preferred embodiment of the apparatus according to the invention, dielectric is oil.
In the other preferred embodiment of the apparatus according to the invention, protection gas contains sulfur hexafluoride.
In the other preferred embodiment of the apparatus according to the invention, casing have first part, described first
Divide in the shell for being configured to project into electric utility in state after mounting and is surrounded by dielectric.
In the other preferred embodiment of the apparatus according to the invention, casing have second part, described second
Divide and is configured to project into the shell for surrounding resistor column and is enclosed in state after assembling by protection gas bag.This is favourable,
Because being integrated into Surge Protector element by sleeve portion, described device can have especially economical space saving with it is particularly lightweight
Ground construction, to save the cost in production and transportation.
In the other preferred embodiment of the apparatus according to the invention, to lead to the contact between resistor column and casing
The entrance in region is provided with service cover.In protector, the service cover is also generally referred to as inspection hole, because technical staff exists
The entrance for leading to the component positioned at enclosure interior is obtained after opening cover board.
In the other preferred embodiment of the apparatus according to the invention, contact device can be by being arranged on shell
Driving device driving.This have the advantage that in this way, can not open the shell area for protecting edge of drawing last breath
In the case of realize that Surge Protector is switched on or switched off.
In the other preferred embodiment of the apparatus according to the invention, driving device is manual driving device.This is
It is advantageous, because for example at low cost and manual actuation can be simply formed using hand-crank device.
In the other preferred embodiment of the apparatus according to the invention, driving device is electric driver.This is that have
Benefit, it, can be by control device at the scene or by distant because electric driver is for example by the electric driver of motor
It controls device and passes through control station automatic.
In order to more preferably illustrate the present invention, in the diagram:
Fig. 1 shows the embodiment of the apparatus according to the invention.
Fig. 1 shows the embodiment of the apparatus according to the invention 1, the electric utility 2 that device 1 is used to be insulated with dielectric 5
Overvoltage protection.The facility is oil-insulation high-tension transformer, has the shell 20 filled up with oil 5.Regulation has with resistance member
The resistor column 3 of part 19, resistor column 3 are arranged in shell 4, protective gas 6, such as sulfur hexafluoride of the shell 4 full of electrical isolation
(SF6).Casing 7 for electric utility 2 to be connect with resistor column 3 has first part 17, and first part 17 is in assembled state
In project into the shell 20 of electric utility 2 and surrounded by dielectric 5.First flange 15 connects shell 20 and casing 7.Casing
7 second part 18 is projected into shell 4 and is surrounded by protection gas 6, and shell 4 surrounds resistor column 3.Second flange 14 is by shell 4
It is connected with casing 7.
In shell 4 regulation have the contact device 8,9,10,11 that can mechanically drive from hull outside, for be closed and/
Or the electrical connection between separation resistor column 8 and casing 7.Resistive element is metal-oxide semiconductor (MOS), is determined being lower than by structure
It is almost non-conductive when fixed voltage, but while being higher than the voltage, can be very well conductive.As for contact device 8,9,10,
11 driving device uses the manual driving device 12 with hand-crank.It is accomplished that with this, establishes or interrupt 3 He of resistor column
Conductive connection between casing 7 without aspirate protection gas and then by technical staff pass through service cover 13 be turned off manually or in
Connection breaking.Which greatly simplifies the uses of described device, because described device can supply with being fully assembled, and are debugging
It also can easily safeguard later.It, also just no longer must be as current in the past due to eliminating any in-site installation of device
Adapter ring or switching shell are installed in scene between casing 7 and protector housing 4 like that, not to be adapted to mutually when necessary
Flange connection.
Contacting device has threaded rod 9, and threaded rod 9 is fixedly connected with contact 8.Contact 8 is configured to bolt, in guide member
It can slidably be shifted in 21.If bolt 8 is inserted in the cooperation contact 16 of 7 side of casing, conductive connection is established.If bolt 8 is complete
It is complete that it is withdrawn into 21 side of guide member entirely, then constitutes external series gap 22, external series gap realizes the disconnection of safety by protection gas.Spiral shell
Bar 9 is retained in transmission device 10, and regulation has the second rod piece 11 in transmission device 10, so that the rotation of the second rod piece 11 is via biography
Dynamic device 10 is transmitted on screw rod, so that threaded rod is moved along the axis for being parallel to resistor column.In the simplest case,
Two rod pieces 11 are provided with type exterior feature or screw thread thus, are configured to relative to screw flight complementation.In the engagement state shown in,
The corresponding rotation of the second rod piece driven from driving device 12 can screw screw rod and bolt 8 to the direction of driving device, with this
Kind mode forms external series gap 22.
