Description
Technical field
The present invention relates to the communications fields, are situated between in particular to a kind of determination method and device of combinational gap, storage
Matter.
Background technique
With the development and the improvement of people's living standards of electric system, power consumer is to power quality and power supply reliability
Requirement be also gradually increased, especially for important power customer, it is desirable that power grid can constantly provide it good
Electric energy service, also, itself for power grid, having a power failure or do not have a power failure less is that it obtains economic benefit and social benefit most
Main path.For guarantee power system security, reliable, economical operation, shorten the transmission line of electricity interruption maintenance time to the maximum extent,
The good health state for guaranteeing equipment needs to carry out live-line maintenance operation to transmission line of electricity.
The livewire work of power transmission lines overhauling refers in the case where transmission line of electricity does not have a power failure, and implements test, inspection to route
It repairs, be transformed and more change jobs, guarantee that power grid can still provide for normal power supply during this period.Livewire work has become transmission line of electricity inspection
The important means and method repair, detect, being transformed.Interconnection is realized between current each bulk power grid, it is necessary to fully ensure that the peace of interconnection
Full stable operation, livewire work will also play a great role in the maintenance work of interconnection.
In order to guarantee livewire work personnel safety during livewire work during design livewire work, field path mistake is passed in and out
Combinational gap needs to meet safe distance specification in journey.
The definition of Live Working Complex Gap: livewire work personnel position to electrical body (conducting wire, insulator chain) and
The minimum three-dimensional sum of the distance of grounding body (shaft tower) is arranged if the smallest combined distance meets live-working safety specification
Approach course meets safety.
At present in livewire work the calculation method of combinational gap mainly according to design drawing or site inspection, exist
Following difficult point:
Simplified two-dimension drawing is not accurate: two-dimentional drawing is to simplify drawing, is the simplification of live complex situations, such as corner angle
It spends small tower to be reduced to tangent tower, insulator chain is reduced to straight line etc., in transmission line construction work progress, in fact it could happen that
The inconsistent situation with design drawing state, such as insulator chain hanging position, in the process of running, equipment is it is possible that become
Shape, such as shaft tower inclination, insulator chain bending, do not carry out drawing update etc., above-mentioned change when substituting equipment during transporting inspection
It is inconsistent with actual scene that change will lead to basic data, and can not carry out three-dimensional measuring, the standard of data so that influence is developed programs
True property；
Artificial site inspection is easily omitted: in the case where no drawings, artificial site inspection is needed, it, can since shaft tower is higher
Details omission can occur, acquisition information is caused to be not enough to realize final job requirements.Such as site inspection can not be identified clearly
The number and length of insulator chain, if going to formulate maintenance solution on the basis of reconnoitring at the scene, in fact it could happen that sent out when practical maintenance
The case where existing insulator chain number is more than existing information, the work tool curtailment of preparation is to meet construction demand, then
Need to reformulate scheme, secondary construction operation；
Combinational gap checklist is revealed: the livewire work scheme designed according to drawing and site inspection is only according to two-dimensional geometry
The smallest combinational gap value of feature calculation cannot carry out LINEAR CONTINUOUS security combination gap core to the overall process in disengaging strong electrical field
It tests.
