Abstract
The utility model relates to a yellow-green-red phase sequence insulator. Without affecting the electrical characteristics of the insulators, such as insulativity, intensity, etc., pigments of yellow, green and red colors are added to the synthetic rubber products, and the insulators are divided into three colors of yellow, green and red instead of the unified dark red for production. The beneficial effects of the utility model are that, the function is single and simple, and the patrol gets intuitional; the insulators are mounted on the line hardware in a sequence of yellow, green and red, so that in a newly built line, wires with insulators of the same color are connected so as to prevent the misconnection of the phase sequence, being convenient and practical. If an accident happens on the line and a trip-out occurs, the patrol personnel performs line patrol based on the line phase sequence according to the commands of the scheduling department and finds the fault point, so that the time of first-aid repair is saved and the working efficiency is greatly improved, providing a food popularization prospect.
Description
Technical field
The utility model relates to yellowish green red three phase sequences identification of power circuit.
Background technology
In new frame 10kV circuit or maintenance line work; often use the iron wire colligation for the phase sequence of distinguishing line conductor on the corresponding gold utensil of circuit with a kind of metal phase-sequence plate of the ABC of sign three-phase; through all the year round hardships corrosion; writing meeting corrosion is smudgy above the phase-sequence plate; for the identification phase sequence causes difficulty;, make troubles to the workmen, reduce operating efficiency.
Summary of the invention
The purpose of this utility model is exactly to overcome the defective that prior art exists, and a kind of insulator of more intuitively identification three-phase phase-sequence is provided.
For achieving the above object, the technical solution of the utility model is: by getting in touch with insulator producer, under the electricity characteristic prerequisites such as the insulation that does not affect insulator, intensity, in having synthetic rubber articles, add the pigment of yellowish green red three colors, insulator by unified kermesinus, is distinguished into yellowish green red three colors and manufactures.
Characteristics of the present utility model are that function singleness is easy, inspection is directly perceived, installing insulating peace, only need to connect the wire of insulator same color in new stringing road according to yellowish green red three orders on line hardware, just can avoid the phase sequence wrong, convenient and practical.Running under the line accident trip condition, the tour personnel directly carry out line inspection according to line phase-sequence detection according to traffic department's order, and the looking up the fault point is made an appointment for repair joint, greatly increases work efficiency, and has stronger promotion prospect.
Description of drawings
Accompanying drawing 1 is schematic diagram of the present utility model;
Embodiment
As shown in Figure 1, yellow insulator 1, green insulator 2, red insulator 3 are installed on the line according to yellowish green red order, made the staff on new stringing road and maintenance circuit, pick out very intuitively line phase-sequence detection, save the plenty of time for work, increase work efficiency.
Claims (1)
