Description

Technical Field

[0001] The utility model relates to the technical field of circuit fault monitoring, in particular to a 10kV circuit fault comprehensive monitoring and alarm device. Background Art

[0002] The 10kV line of the substation generally adopts two-stage or three-stage current protection, that is, current quick-break or time-limited quick-break and overcurrent protection. We can make a preliminary judgment based on the action of the substation fuse protection. If the line has a current quick-break protection action, it can be judged that the fault point is generally caused by a direct circuit breaker of two or three phases of the line, and the fault point is more likely to be on the main line or a line close to the substation. Therefore, people will install monitoring and alarm devices on each branch circuit of the 10KV circuit to promptly alarm and carry out maintenance when a fault occurs.

[0003] When the existing 10kV circuit fault integrated monitoring and alarm device is installed and used, it is generally fixed to the electric pole through a mounting frame. During the fixing process of the mounting frame, the power construction workers need to tighten multiple bolts at high altitude to tightly connect the mounting frame and the electric pole, which takes a long time. Utility Model Content

[0004] The present invention relates to a 10kV circuit fault integrated monitoring and alarm device, which solves the problem that the existing 10kV circuit fault integrated monitoring and alarm device is generally fixed to a utility pole through a mounting frame during installation and use, and during the fixing process of the mounting frame, power construction workers need to tighten multiple bolts at high altitude to tightly connect the mounting frame and the utility pole, which takes a long time.

[0005] In a first aspect of the present disclosure, a 10kV circuit fault comprehensive monitoring and alarm device is provided, which specifically includes: a support frame; the support frame is in contact with a utility pole, a transformer is installed on the top of the support frame, and a relay, a battery and a signal transmission module are installed on the top of the transformer by bolts; an arch frame is connected to the inside of the support frame, and the arch frame is in contact with the utility pole; two stress-bearing strips are connected to the outside of the support frame, and the stress-bearing strips are connected to the arch frame.

[0006] Furthermore, the transformer is connected to two coil lead pins of the relay, the positive pole of the battery is connected to one of the normally closed contact pins of the relay, the positive pole of the signal transmitting module is connected to the other normally closed contact pin of the relay, and the negative pole of the battery is connected to the negative pole of the signal transmitting module. When a circuit breaker fault occurs in the kV circuit, the internal coil of the relay stops supplying power, and the internal moving contact of the relay is in contact with the two normally closed contacts, so that the battery and the signal transmitting module are energized, and the circuit breaker fault alarm information is transmitted to the integrated monitoring terminal through the signal transmitting module.

[0007] Furthermore, the bottom side of the arch frame is in sliding contact with the support frame, guide grooves are provided on both sides of the support frame, and connecting rods are provided at both ends of the arch frame, and the connecting rods are slidably connected in the guide grooves.

[0008] Furthermore, a middle groove is provided in the middle of the stress-bearing strip, and end grooves are provided at both ends of the stress-bearing strip. The middle groove and the end grooves are in the same direction. The two stress-bearing strips are in contact with each other, and the two stress-bearing strips are in opposite directions.

[0009] Furthermore, one of the stress-bearing strips is provided with two positioning holes inside, and the other stress-bearing strip is provided with two positioning blocks outside, and the positioning blocks are inserted into the positioning holes.

[0010] Furthermore, the connecting rod passes through the two end grooves, and the end of the connecting rod is in contact with the stress-bearing strip.

[0011] Furthermore, a screw is provided on the outside of the support frame, the screw passes through the two middle grooves, and a nut is connected to the external thread of the screw, and the nut is in contact with the stress-bearing strip. When the support frame is in contact with the electric pole, the nut is turned by a wrench, and the nut drives the two stress-bearing strips to move outward, and the stress-bearing strips drive the arch frame to move inward, thereby reducing the distance between the arch frame and the electric pole, making the arch frame in close contact with the electric pole, thereby clamping and fixing the support frame, making the installation and fixation of the device easier and quicker.

[0012] The utility model provides a kV circuit fault comprehensive monitoring and alarm device, which has the following beneficial effects:

[0013] When the utility model is in use, high voltage electricity is converted into low voltage electricity through a transformer to supply power to the internal coil of the relay, the internal moving contact of the relay is in a separated state from the two normally closed contacts, so that the battery and the signal transmitting module are in a disconnected state; when a short circuit fault occurs in the kV circuit, the internal coil of the relay stops supplying power, the internal moving contact of the relay is in a contact state with the two normally closed contacts, so that the battery and the signal transmitting module are in a powered-on state, and the short circuit fault alarm information is transmitted to the integrated monitoring terminal through the signal transmitting module, so that circuit maintenance personnel can arrive in time for maintenance and restore normal power supply.

[0014] In addition, by plugging and cooperating with the positioning block and the positioning hole, the load-bearing strips are limited to prevent them from falling from a height. When the support frame contacts the telephone pole, the nut is turned by a wrench, and the nut drives the two load-bearing strips to move outward, and the load-bearing strips drive the arch frame to move inward, shortening the distance between the arch frame and the telephone pole, making the arch frame in close contact with the telephone pole, clamping and fixing the support frame, making the installation and fixation of the device easier and faster.

The internal moving contact of the relay 3 is in a separated state from the two normally closed contacts, so that the battery 4 and the signal transmitting module 5 are in a disconnected state. When a circuit breaker fault occurs in the 10kV circuit, the internal coil of the relay 3 stops supplying power, and the internal moving contact of the relay 3 is in a contact state with the two normally closed contacts, so that the battery 4 and the signal transmitting module 5 are energized. The circuit breaker fault alarm information is transmitted to the integrated monitoring terminal through the signal transmitting module 5, so that the circuit maintenance personnel can arrive in time for maintenance and restore normal power supply.
