Description

A mounting and fixing bracket for wireless temperature measuring equipment in a substation

technical field

The utility model relates to a component for a substation, in particular to a mounting bracket for wireless temperature measuring equipment in a substation.

Background technique

A large number of high-voltage equipment and precision instruments are running in the substation to ensure the stable operation of the substation. During the operation of the equipment, the product will generate a certain amount of heat, and the heat will not affect the operation of the equipment if the heat is within a reasonable range. If the temperature is too high, it will cause the high temperature operation of the equipment and affect the life of the equipment, and seriously cause the equipment to malfunction and cause power outages , Unstable power supply, etc., affect the normal power supply of residents, enterprises and institutions. Therefore, the substation uses wireless temperature measurement sensor equipment to monitor the operating temperature of various equipment in the substation in real time to ensure that the temperature of the equipment is in a controllable state. When the temperature exceeds the upper limit of the warning, an alarm is automatically issued to remind the operation and maintenance personnel to deal with it in time. The application of wireless temperature sensor equipment can monitor the operating temperature of the equipment in real time, effectively ensuring the stable operation of the equipment. The existing wireless sensor equipment is installed by pasting and screwing. Since many devices in the substation have been operating outdoors for a long time, the complex environmental conditions and bad weather have an impact on the firmness of the wireless sensor equipment, which may easily cause the temperature sensor to loosen, shake, fall off, etc., not only cannot be collected in real time The operating temperature of the equipment will bring hidden dangers to the operation and safety of the substation. The simple, safe and stable installation and fixing method of the wireless temperature measurement sensor equipment in the substation is an urgent problem to be solved in the temperature measurement and monitoring work of the substation operation.

At present, the installation and fixation of temperature measurement sensor equipment for substation equipment operation is mainly realized by bottom glue sticking and bottom screw fixing. The problems and loopholes in this way are:

1. In the substation indoor switch cabinets and capacitor cabinets, the bottom sticking method is used, which is only suitable for vertical installation and fixing. However, the vertical method is not stable, and the outdoor equipment cannot be applied. The way of pasting is greatly affected by the environment, and it will cause the glue to crack for a long time, causing the temperature sensor equipment to fall off and affecting the normal operation of the substation equipment.

2. There are various substation equipment and equipment, and the bottom screw fixing method needs to be drilled on the existing equipment, which will cause damage to the equipment itself and may affect the operation of the equipment. The method of fixing with single-point screws has poor fastening performance. Fixing with screws is likely to cause a gap between the substation equipment and the sensor, causing the temperature measurement sensor to be electrified, which is extremely harmful to personnel and equipment.

3. The main transformer, knife switch, circuit breaker, lightning arrester and other equipment in the substation are in a long-term outdoor operation state. The environment has a great influence on the stability of the fixation. Paste and simple fixation will increase with time or in bad weather. Loosening, cracking, falling off, etc., will bring hidden dangers to the operation of substation equipment.

Contents of utility model

The purpose of the utility model is to provide a mounting and fixing bracket for the wireless temperature measuring equipment in the substation, which can effectively improve the fixing stability of the wireless sensing equipment in the substation and prevent the temperature measuring sensor from loosening or falling off.

The technical solution adopted is:

A mounting bracket for substation wireless temperature measuring equipment is composed of a bracket arm connected to a bracket ring body, and is characterized in that:

There is an opening in the ring body of the bracket, and a positioning chute is arranged horizontally in the bracket arm;

The opening end of the support arm is docked with the opening on the support ring body, the positioning chute communicates with the ring hole of the support ring body, and the support arm and the support ring body are an integral structure formed at one time. The using method of the utility model:

Select a fixing bolt on the substation itself, remove the nut on the bolt, put the bracket ring body on the bracket on the screw, then screw the nut on the screw, and tighten it, so that the bracket is firmly fixed on the shell of the substation .

Set the wireless temperature sensor at a suitable position on the bracket arm. There is a built-in nut at the bottom of the wireless temperature sensor. Screw a screw from bottom to top through the positioning chute on the bracket arm and set it on the built-in nut at the bottom of the wireless temperature sensor. Tighten the inside, and securely fix the wireless temperature sensor on the bracket arm.

Advantage of the utility model:

1. Using the fixed wireless temperature measuring equipment of the utility model, the fixing screws on the substation’s own equipment can be used to realize the installation and fixing of the temperature measuring sensor equipment. It has good compatibility and is suitable for installation in indoor and outdoor environments of substations. Equipment temperature sensor equipment installation requirements.

2. The utility model uses the installation bracket to replace the installation method of glue paste and screw simple fixing, realizes simple, safe and stable installation and fixing of sensor equipment, prevents and reduces the occurrence of electrical accidents, and greatly improves the safe operation of electrical devices The level and reliability of power supply provide technical support for the operation and maintenance management of unattended substations, bringing significant power grid benefits and social and economic benefits.

3. Reduce the damage caused by the installation of wireless temperature measurement sensors to substation equipment, avoid the safety hazards caused by the instability of sensor equipment, and improve the fastening degree of temperature measurement sensor equipment while ensuring the accuracy of temperature measurement data. The installation fix provides support and service.
