Abstract
The invention discloses an icing measurement device, which comprises an ice storage box [1], a bracket [2] and a wire clamping unit [3]. During the off-line ice sample taking process, the weight of the entire icing measurement device is measured, and then the wire clamping unit [3] is removed. After that, a bolt [37] is assembled and a wire clip [34] is opened. The wire clip [34] is clamped onto a wire. The wire clamping unit [3] is tightened and then the bolt [37] is screwed onto the wire clamping unit [3]. In this way, the ice coated onto the wire above the ice storage box [1] can only be removed by means of an ice skate blade. After that, the bolt [37] assembled onto the wire clamping unit [3] is unscrewed, and the weight of the ice and the entire icing measurement device is measured. Therefore, the icing weight of the wire of a certain length can be obtained. According to the technical scheme of the invention, the icing thickness of the wire can be calculated according to the length of the ice storage box.
Description
Technical field
The invention mainly relates to transmission line of electricity prevent and reduce natural disasters field, refer in particular to a kind of icing measurement apparatus, it is possible to sample during for wire icing of transmission line.
Background technology
Transmission line of electricity path topography and geomorphology is complicated, it is easy to by the impact of mima type microrelief, microclimate condition, particularly mountain route, comes interim owing to temperature is at about 0oC for cold wave at the beginning of Xinjiang region 12 months, now meets sleety weather, very easily cause powerline ice-covering. The serious icing of transmission line of electricity can cause coating ice falling on wire overloading broken string, covering ice for insulator flashover, wire to jump and cause line tripping etc., have a strong impact on the properly functioning of transmission line of electricity, the tripping operation that current icing causes become destroy continue external force, thunderbolt, the fourth-largest tripping operation factor after bird pest, particularly icing, wire breaking, the emergency repair time length and easily cause second accident of falling after tower. Therefore, it is necessary to ice covering thickness is measured, to understand the electric power line ice-covering thickness of different regions, provide foundation for the transformation of old line ice coating and new line construction. What the measurement employing of current icing was more has on-line method and off-line process, and on-line method measures ice covering thickness mainly through measure traverse line tension variation, but owing to field wires ice covering thickness is inconsistent, circuit each shelves icing is inconsistent, it is easy to cause measurement error bigger. Off-line measurement generally relates to problem of sampling, owing to icing kind is varied, touches both to fall with one as rime, snow rime, brings very burden to field investigation and sampling. In order to improve off-line sampling precision, it is contemplated that a kind of ice covering thickness off-line measurement device of design.
Summary of the invention
In order to solve the problem that the sampling of electric power line ice-covering thickness off-line measurement is difficult, sampling precision is low, it is contemplated that a kind of electric power line ice-covering thickness off-line sampler of design, to facilitate powerline ice-covering off-line to sample, improve sampling precision.
The technical solution used in the present invention is:
When off-line takes ice sample, measure whole icing measurement apparatus weight, take off bolt on clamping wire installation, open wire clamp, wire clamp is clipped on wire, tighten bolt on clamping wire installation, Square wire overlying ice on ice filling box is taken off by handy skates, unclamps bolt on clamping wire installation, measures the weight of icing and whole icing measurement apparatus, obtain icing weight on certain length wire, calculate wire icing thickness according to ice filling box length gauge.
Described icing measurement apparatus, ice filling box top end opening, and width is much larger than diameter of wire.
Described icing measurement apparatus, its clamping wire installation has tread plate.
Described bolt has spring.
Employing is the present invention have an advantage that
1, ice filling box top end opening and width are much larger than diameter of wire, facilitate icing on wire to drop in ice filling box.
2, having tread plate on clamping wire installation prevents icing measurement apparatus in taking ice process from sliding.
3, bolt has spring and may remain in sampling process the pressure after wire clamp place coating ice falling, it is prevented that icing measurement apparatus moves.
In sum: icing measurement apparatus, it is possible to facilitate powerline ice-covering off-line to sample, sampling precision is improved.
