Embodiment 1

[0044] Embodiment one: if figure 1 and figure 2 , a fuse for wind power protection, including a mounting base 26 for installing a fuse body 1, and a fuse feedback device is provided on the mounting base 26. The fusing feedback device includes a trigger 2, and brackets 18 are installed on both sides of the trigger 2, and the brackets 18 are connected with the fuse body 1 by screws. The side of the mounting base 26 close to the fuse 1 is provided with an arc shield 22 , the height of the arc shield 22 is greater than that of the fuse 1 , and when the fuse 1 is inserted or removed, the arc shield 22 prevents the arc from spreading.

[0045] combine image 3 and Figure 6 , both sides of the mounting base 26 are provided with positioning grooves 27, and the positioning grooves 27 are embedded with a clamping contact 11. The clamping contacts 11 include two pieces of contacts 12, and the positions of the two positioning grooves 27 have been determined, so The two clamping cont...

Embodiment 2

[0051] Embodiment 2: A fuse for wind power protection, including a mounting seat 26 for mounting the fuse body 1 , and a fuse feedback device is provided on the mounting seat 26 . The fusing feedback device includes a trigger 2, a linkage mechanism and an interaction mechanism.

[0052] Such as Figure 7 The trigger 2 is provided with a fuse 4 and a striker 3 connected to the fuse 4. The trigger 2 is also provided with a first spring 5. One end of the first spring 5 abuts against the inner wall of the trigger 2, and the other end Sleeved on the impact piece 3, the impact piece 3 is in the shape of a stepped shaft, so the first spring 5 can be engaged with the shoulder of the impact piece 3, and the two form a relative restraint to be installed together; when the fuse 4 is tightened, the impact piece 3 Push the first spring 5 to move to the left so that the first spring 5 is in a compressed state, so the first spring 5 retains elastic potential energy. The fuse 4 passes throu...

Embodiment 3

[0054] Embodiment 3: A replacement method for the fusing feedback device of Embodiment 1 or Embodiment 2, comprising the following steps:

[0055] Step 1: Remove the old fuse 1 and the old fuse feedback device, and take the fuse 1 and fuse feedback device to be used;

[0056] Step 2: Take two brackets 18 to cooperate with the two ends of the trigger 2 respectively, take screws and penetrate into the first connecting groove 20 on the brackets 18, and pre-install the brackets 18 and the cover plates 19 on both sides of the fuse body 1 through two screws. fixed;

[0057] Step 3: Rotate the trigger 2 around the axis of the two screws, and when the second connection groove 21 is rotated to the matching position of the cover plate 19 with the rotation of the bracket 18, then take the screw and insert it into the second connection groove 21, and tighten all the screws to complete the assembly of the trigger 2 and the fuse 1;

[0058] Step 4: Take the fuse body 1 assembled in step 3...

Abstract

The invention discloses a fuse for wind power protection and a replacement method of a fusing feedback device of the fuse. According to the main point of the technical scheme, the fuse comprises an installation base for installing a fuse link; the installation base is provided with the fusing feedback device; the fusing feedback device comprises a trigger, a linkage mechanism and an interaction mechanism; the trigger is connected with the fuse link in parallel; the voltage on the trigger is increased when the fuse link is fused; when the fuse link is fused, the trigger actuates the linkage mechanism to generate an action; the action of the linkage mechanism triggers the action of the interaction mechanism; and the action of the interaction mechanism is converted into an electric signal and is transmitted to an external data interface. The electric signal is transmitted to the positions of a monitor room and the like through a microswitch according to the fusing condition of the fuse link; multiple pieces of position information can be timely and accurately obtained by power maintenance personnel; and field investigation is not needed, so that manpower is saved; and the efficiency is improved.

Description

technical field [0001] The invention relates to a protection device for a wind power generation system, in particular to a replacement method for a fuse for wind power protection and a fuse feedback device thereof. Background technique [0002] The fuse is based on the fact that after the voltage exceeds the specified value for a period of time, the heat generated by itself melts the melt, thereby disconnecting the circuit; a voltage protector made by using this principle. Fuses are widely used in high and low voltage power distribution systems and control systems, as well as electrical equipment. As short circuit and overvoltage protectors, fuses are one of the most commonly used protection devices. [0003] At present, the Chinese patent with the publication number CN204632657U on the market discloses a light display fuse type isolating switch. The card boards are fixedly connected by screws, and a transparent cover is placed on the handle cover outside the luminous devic...
