Description
Technical field
The present invention relates to electroscopy equipment, and in particular to a kind of 10KV electrical verifications insulating bar.
Background technology
With the continuous quickening of power grid construction, distribution line also becomes to become increasingly complex, and for operation teams and groups, faces
All kinds of grid switching operations it is more and more frequent.On distribution line, block switch, demarcation switch and prepayment metering switch are equal on post
It is the integration apparatus that vacuum circuit breaker combines with disconnecting link.Find that switch exists during grid switching operation by long-term practice
The situation that breaker just draws (conjunction) disconnecting link in false isloation state, this will bring serious potential safety hazard.
According to distribution《Safety》5.2.6.7 the regulation of bar：Position detection should be with equipment physical location after controller switching equipment operation
It is defined, when can not see physical location, indirect method such as plant machinery position instruction, electrically instruction, powered display dress should be passed through
Put, the change of the signal such as instrument and various remote measurements, remote signalling judges device location.During judgement, should at least there are two non-same originals
Manage or corresponding change occurs for non-homogeneous instruction, and the instruction of all these determinations occurs to correspond to change simultaneously, can confirm
The equipment has operated in place.
According to the characteristics of 10kV distribution line upper switch, breaker operator is judged with round-about way in practical operation
Whether in place when, following drawback be present：
Whether first, being operated in place for outdoor breaker switch, operating personnel can only uniquely lean on the machinery instruction of " seeing " switch
Position judges, lacks the electrical verification process confirmed after operation to circuit-breaker status, is just drawn disconnecting link the operation of (conjunction) lock, if
, will there is serious security hidden trouble when vacation point phenomenon occurs in breaker.
Second, on-pole switch installation site is higher, operating personnel can not enter on ground to the physical location after breaker operator
Row electrical verification, if realizing that electrical verification works using bar mode is stepped on, and there is certain potential safety hazard, also increase operating personnel's
Labor intensity and the relatively low situation of efficiency.
Although third, being equipped with mechanical locking device between breaker and disconnecting link, operating switch has quite a few
Blocking device has damaged, and the divide-shut brake machinery indicators for also having some switches have come off or indicated not in place, indivedual behaviour in addition
Make personnel and the performance of switch is understood not deep enough, the behavior of misoperation happens occasionally, and whether in place to judge breaker operator, such as
Fruit is only judged that the behavior for easily inducing operation against rules occurs, and is transported to distribution only with round-about way in the prior art
Dimension leaves potential potential safety hazard, it is possible to the maloperation event of on-load broaching tool lock occurs.
The content of the invention
It is an object of the invention to solve prior art to lack the electrical verification process for confirming circuit-breaker status after operation, easily
Maloperation event is caused to occur, and the problem of larger potential safety hazard be present in existing electrical verification mode, the present invention provides a kind of 10KV and tested
Electricity insulating bar.
The present invention is achieved through the following technical solutions：
A kind of 10KV electrical verifications insulating bar, including action bars, the electrical verification probe on action bars top is arranged on, passes through company
Lead and the electrical verification display of electrical verification probe connection are connect, the electrical verification display is fixed on action bars by connection fixture.
The setting of the structure in the present invention, operation and the electrical verification work for the controller switching equipment being effectively applicable on 10kV circuits,
Particularly divide-shut brake machinery indicator has been come off or has indicated breaker not in place, has been increased to the shape after breaker grid switching operation
The electrical verification operating procedure of state, the accuracy of judgement is effectively ensured, also, the present invention can prolong according to work on the spot needs, action bars
Length, operating personnel is carried out the operation and can of eminence equipment on ground and carry out electrical verification work, the present invention can
Need to mitigate operating personnel on electric pole or framework to continue up step on bar, transposition could complete the labor intensity that electrical verification works,
Greatly reduce the labor intensity of operating personnel.
The present invention is suitable for transformer on isolation switch, the grid switching operation of fuse switch and electrical verification work and stand
Electrical verification, electrical verification can also be carried out to the high and low pressure side of transformer using 0.4~10kV electrical verifications head.
Further, electrical verification probe includes being socketed in the cap body on action bars top, be connected with cap body and with action bars
The vertically disposed probe in axis.
By the setting of said structure, the effect for effectively reaching electrical verification is not only only capable of, and electrical verification operation can also be made more
It is convenient, suitable under different electrical verification operational circumstances, effect is more notable, it can accurately and effectively judge whether switch occurs
Vacation point (vacation is closed) phenomenon, avoids on-load from drawing the dangerous situation of (conjunction) disconnecting link to occur.Moreover, for joint use, this hair
The bright electrical verification for passing through lower floor's alive circuit completion to upper layer circuit, i.e. structure of the invention are carried out to the state after grid switching operation
Electrical verification confirmation is very convenient, and electrical verification operation is more comprehensively and effective.
Also, by the setting of said structure, in addition to the electroscope function of energy realization itself, also expect not with following
The technique effect arrived, i.e. the optimal design-aside of the structure can also effectively realize that 10kV matches somebody with somebody the back brake of online installation site higher device
Operation, avoid manually stepping on bar progress grid switching operation, operation is more safe and simple.
Further, the cap body top is additionally provided with rain cover connection end, and rain-proof is connected with the rain cover connection end
Cover.The present invention also solves the problem of electroscope electrical verification of misty rain day is without rain cover using the action bars with rain cover.
Further, the connection fixture includes insulation connecting plate, the card being fixed on the side of insulation connecting plate
Tooth group；The latch group includes being fixed on the first latch that insulation connecting plate is used to be fixedly connected with action bars wherein on one side
Group, and be fixed on insulation connecting plate another side and be used for the second latch group that electrical verification display is fixedly connected.The insulation
