Description

Insulator lightning arrester fuse combination device

Technical Field

The utility model relates to the field of overvoltage protection products, in particular to an insulator lightning arrester fuse combination device.

Background technique

The drop-out arrester is an optimized product of the zinc oxide arrester. It can detect, replace and repair the arrester through the insulated switch lever without power outage, which greatly reduces the work intensity and time of power maintenance personnel. It is particularly suitable for hospitals, airports, stations, chemical plants and other places where power outages are not suitable. The electrical parameter performance of the product is the same as that of the zinc oxide arrester. In addition, the drop-out arrester contains a fault indicator device (disconnector). When the arrester is abnormal or fails, the power frequency short-circuit current is used to activate the disconnector, so that the grounding terminal of the disconnector is automatically disconnected, the arrester components fall off, and the operation is stopped to prevent the accident from expanding further, and it is easy for the maintenance personnel to find it in time for maintenance and replacement.

The drop-out fuse is installed on the branch line of the 10kV distribution line to reduce the scope of power outage. Because it has an obvious disconnection point and has the function of an isolating switch, it creates a safe working environment for the maintenance section lines and equipment and increases the sense of security of the maintenance personnel. It is installed on the distribution transformer and can be used as the main protection of the distribution transformer. Therefore, it has been popularized in 10kV distribution lines and distribution transformers.

In the existing power equipment, the arrester and the fuse are installed separately, which results in low structural stability, inconvenient maintenance, and a large workload when installing or replacing the arrester and the fuse separately.

Detailed ways

The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

An insulator lightning arrester fuse combination device comprises a first bracket 10, on which a drop-out arrester 1, a first post insulator 3 and a drop-out fuse 2 are respectively mounted, the first post insulator 3 is mounted on the parallel section of the first bracket 10, the drop-out arrester 1 and the drop-out fuse 2 are respectively mounted at the two ends of the first bracket 10, the lower end of the first post insulator 3 is mounted on a second bracket 9, the two ends of the second bracket 9 are respectively connected with a strip line disconnector and a second post insulator 6, the strip line disconnector 8 is connected to the drop-out arrester 1, and one end of the second post insulator 6 is provided with a link 7, which is connected to the drop-out fuse 2.

As shown in FIG. 1 , the first bracket 10 is a bow-shaped bracket, and the second bracket 9 is a mouth-shaped bracket.

Preferably, the first bracket 10 adopts a bow-shaped bracket, and the two ends of the bow-shaped bracket are in an inclined state, which is convenient for the drop-type lightning arrester 1 and the drop-type fuse 2 to turn sideways and detach when a fault occurs due to gravity. The second bracket 9 adopts a mouth-shaped bracket with many connecting end faces and a stable supporting effect.

As shown in FIG. 1 , the second bracket 9 is connected to the first post insulator 3 , the second post insulator 6 and the wire disconnector 8 respectively through fixing bolts 4 .

As shown in FIG. 1 , a fixing bracket 5 is provided at the lower end of the second bracket 9 and is connected via fixing bolts 4 .

Preferably, the entire device is easily installed and fixed by a fixing bracket 5, and is easily disassembled by connecting with fixing bolts 4.

As shown in FIG. 1 , the fixing bracket 5 is in a side U shape, and the inner grooves of the bending parts at both ends of the fixing bracket 5 are chamfered, and the width of the bracket is the same as the width of the second bracket 9 .

Since the fixing bracket 5 adopts a side U shape, the fixing bracket 5 can be directly inserted into the installation position. Since the width of the fixing bracket 5 is the same as the width of the second bracket 9, the supporting surface of the fixing bracket 5 and the installation position is increased, and the supporting effect is good and more stable. Since the lower end of the fixing bracket 5 is also provided with a supporting bolt threadedly connected to the inner wall of the fixing bracket 5, the upper and lower end surfaces of the fixing bracket 5 are tightly fitted with the installation position by using the supporting bolts, and disassembly and installation are more convenient. In addition, since the inner groove chamfers at the bending parts of the two ends of the fixing bracket 5 can prevent the side end surface of the fixing support from fitting with the installation position, and since the material of the installation position is usually metal, rust can be avoided to reduce the stability of the fixing bracket 5.

The working process of the utility model is as follows: the utility model supports the drop-out arrester 1 and the drop-out fuse 2 by using the first bracket 10 at the upper and lower ends, and the lower end adopts the first support insulator 3 and the second support insulator 6 to cooperate with the second bracket 9 for support, the supporting effect is good, and the disassembly and installation can be carried out at the same time, and the second bracket 9 adopts a square bracket with many connection ends, and the supporting effect is stable, and the lower end of the second bracket 9 adopts a fixed bracket 5 for support and installation, because the fixed bracket 5 adopts a side U shape, the fixed bracket 5 can be directly inserted into the installation position, and because the fixed bracket 5 The width is the same as that of the second bracket 9, the supporting surface of the fixed bracket 5 and the part to be installed is increased, the supporting effect is good and more stable, because the lower end of the fixed bracket 5 is also provided with a supporting bolt threadedly connected to the inner wall of the fixed bracket 5, the upper and lower end surfaces of the fixed bracket 5 are tightly fitted with the belt installation part by using the supporting bolt, and the disassembly and installation are more convenient, and the inner groove chamfers at the bending parts of the two ends of the fixed bracket 5 can prevent the side end surface of the fixed support from fitting with the belt installation part, and since the material of the installation part is usually metal, rust can be avoided to reduce the stability of the fixed bracket 5.
