Abstract
The utility model discloses a high-tension line column type porcelain insulator which comprises a solid porcelain core rod (1), a porcelain core rod base (2) arranged on the lower portion of the solid porcelain core rod (1), and an umbrella skirt sheath (3) arranged on the outer edge of the solid porcelain core rod (1). The high-tension line column type porcelain insulator is characterized in that the top of the solid porcelain core rod (1) extends toward two sides, and a mounting groove (4) used for fixation is formed at the upper end of the solid porcelain core rod (1). According to the high-tension line column type porcelain insulator, the mounting groove is connected with a fixing sleeve used to fix the high-tension line column type porcelain insulator in sleeved mode so that installation is convenient; moreover, a fixing threaded rod is connected between the solid porcelain core rod and the porcelain core rod base so that the high-tension line column type porcelain insulator can be effectively prevented from falling off a high tension overhead insulation line. The high-tension line column type porcelain insulator is long in service life, safe and reliable, and low in maintenance cost, and has good application prospects.
Description
Technical field
The utility model relates to the high voltage protective technical field, is specifically related to a kind of column type porcelain insulator of high-voltage line.
Background technology
In electric power system, long-distance transmissions for electric weight, the high voltage overhead insulated wire is widely used, the such high voltage overhead insulated wire in thunderstorm weather, meet with the lightning-caused breaking problem and just be the trend that rises year by year, brought larger hidden danger for the normal transmission of electric weight, safe and reliable coefficient reduces greatly, therefore need in the high voltage overhead power circuit, adopt column type porcelain insulator of high-voltage line, but existing column type porcelain insulator of high-voltage line adopts bolt to fix more, and it is very inconvenient to install, and easily causes from the high voltage overhead insulated wire to come off, safe operating life is shorter, and maintenance cost is also higher.
The utility model content
Adopt bolt to fix in order to solve column type porcelain insulator of high-voltage line of the prior art, it is very inconvenient to install, and exist easily to come off from the high voltage overhead insulated wire, safe operating life is shorter, and maintenance cost is higher problem also, a kind of column type porcelain insulator of high-voltage line that the utility model provides, easy for installation, long service life, safe and reliable, maintenance cost is lower, has a good application prospect.
In order to address the above problem, technical solution adopted in the utility model is:
A kind of column type porcelain insulator of high-voltage line, comprise solid porcelain core rod, be arranged on the porcelain core rod base of solid porcelain core rod bottom and be arranged on umbrella sheath on the solid porcelain core rod outer rim, it is characterized in that: extend to both sides at the top of described solid porcelain core rod, the mounting groove that is formed for fixing in the upper end of solid porcelain core rod.
Aforesaid a kind of column type porcelain insulator of high-voltage line is characterized in that: be connected with standing screw between described solid porcelain core rod and the porcelain core rod base, described standing screw extends the bottom of porcelain core rod base, and is socketed with nut.
Aforesaid a kind of column type porcelain insulator of high-voltage line is characterized in that: the quantity that is arranged on the umbrella sheath on the solid porcelain core rod outer rim is four.
The beneficial effects of the utility model are: the utility model is by being used for the fixedly fixed cover of column type porcelain insulator of high-voltage line in the mounting groove socket, easy for installation, and between solid porcelain core rod and porcelain core rod base, be connected with standing screw, can effectively prevent from coming off on the high voltage overhead insulated wire, long service life, safe and reliable, maintenance cost is lower, has a good application prospect.
Description of drawings
Fig. 1 is the structural representation of the utility model line pole type porcelain insulator.
The implication of mark is as follows in the accompanying drawing:
1: solid porcelain core rod; 2: the porcelain core rod base; 3: umbrella sheath; 4: mounting groove; 5: standing screw; 6: nut.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of column type porcelain insulator of high-voltage line, comprise solid porcelain core rod 1, be arranged on the porcelain core rod base 2 of solid porcelain core rod 1 bottom and be arranged on the umbrella sheath 3 on solid porcelain core rod 1 outer rim, extend to both sides at the top of solid porcelain core rod 1, the mounting groove 4 that is formed for fixing in the upper end of solid porcelain core rod 1, by in mounting groove 4 sockets, being used for the fixedly fixed cover of column type porcelain insulator of high-voltage line, easy for installation, having solved column type porcelain insulator of high-voltage line of the prior art adopts bolt to fix, install very inconvenient problem
Be connected with standing screw 5 between described solid porcelain core rod 1 and the porcelain core rod base 2, standing screw 5 extends the bottom of porcelain core rod base 2, and be socketed with nut 6, here between solid porcelain core rod 1 and porcelain core rod base 2, be connected with standing screw 5, can prevent effectively that column type porcelain insulator of high-voltage line from coming off from the high voltage overhead insulated wire, prolong its long service life, guarantee the fail safe of its use.
The column type porcelain insulator of high-voltage line that the utility model is convenient to install, the quantity that is arranged on the umbrella sheath 3 on solid porcelain core rod 1 outer rim is four, can effectively overcome thunderbolt to the impact of high voltage overhead insulated wire, the probability of the appearance hidden danger of the normal transmission of reduction electric weight, specific performance parameter such as following table 1:
The performance parameter of table 1 column type porcelain insulator of high-voltage line of the present utility model
Above demonstration and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
