Description

The instrument and method of a kind of distribution network live line work alternate position of adjustment low-voltage circuit
Technical field
Instrument and method the present invention provides a kind of distribution network live line work with the alternate position of adjustment low-voltage circuit, belong to electricity Power technical field of construction.
Background technology
Distribution network live line work, exactly in the case where ensureing that client do not have a power failure or have a power failure less, to circuit and its attached sets The standby work being constructed, overhauled, rushed to repair.Livewire work can be overhauled directly on powered circuit and equipment.Mesh Before, in distribution network high-low pressure with bar circuit(High pressure 10kV, low pressure 380V)During operation, if operating personnel or equipment are from low-voltage circuit It is alternate by the way that when being operated to high-tension line or low-voltage circuit top device, alternate safe distance deficiency, is usually taken following Three kinds of methods:
1st, low-voltage circuit conducting wire and equipment are subjected to insulation masking;
2nd, directly operated using medial potential working method;
3rd, primary cable phase spacing is expanded using earth potential working method.
Method 1 needs professional to carry out masking work, method 2, due to construction personnel it is relatively near apart from electrical body, it is necessary to Operated again on the basis of masking work, for closely both dangerous to the masking work of electrical body or delay operation Time.
Method 3 is, it is necessary to more people(Per a mutually at least people)Low-voltage circuit is operated, it is necessary to operating personnel it is numerous.
Such as:In high-low pressure upright bar new with bar circuit, new upright bar tower needs to pass through between low-voltage circuit two-phase.But the The two-phase of one phase and the second phase is such as without processing(Low-voltage circuit is subjected to insulation masking or increases the distance between B, C two-phase Add), then it is likely to occur the accident such as short circuit, ground connection caused by new pole erecting contacts low-voltage circuit and occurs.
The existing mode for expanding two phase spacings substantially has two kinds:Using aerial lift device with insulated arm operation, operating personnel is hung with small Arm or insulation ropes traction conducting wire, expand phase spacing;Using insulating bar operation, several operating personnels are on ground or bar, often People controls an operation lever to control phase spacing.
But need job that requires special skills vehicle using aerial lift device with insulated arm operation and be limited to field operation surrounding environment influence.Using Insulating bar working system needs more people to operate at the same time.
