Embodiment 1

[0052] Such as Figure 1~5 As shown, it shows a specific embodiment of the invention.

[0053] Specifically, the sulfur hexafluoride gas density relay in this embodiment includes a measurement assembly, a display assembly, and an installation assembly. The measurement assembly includes at least two measurement elements. The assembly steps of the sulfur hexafluoride gas density relay are as follows:

[0054] In the first step, measure the assembly of the components:

[0055] Refer to attached Figure 1-2 As shown, the measuring assembly includes a first measuring element 100 and a second measuring element 200, the first measuring element 100 includes a gas passage 110 communicating with the sulfur hexafluoride gas in the circuit breaker, and the second measuring element 200 Used to measure the environmental parameters in the air passage 110; the measuring end of the second measuring element 200 communicates with the air passage 101, and the first measuring element 100 is fixe...

Embodiment 2

[0104] In this embodiment, the detailed installation of the sulfur hexafluoride gas density relay is mainly introduced.

[0105] In this embodiment, the first measuring element is a pressure measuring device on the main body of the sulfur hexafluoride gas density relay, that is, a mechanical sulfur hexafluoride density relay, and the second measuring element is a temperature sensor or a pressure sensor.

[0106] Firstly, on the back of the sulfur hexafluoride gas density relay, weld the sensor as the second measuring element, specifically, use welding technology to weld on the back of the instrument display panel; before welding, place the The inductive probe of the sensor extends into the gas-filled joint to realize real-time monitoring of the sulfur hexafluoride gas inside it. When welding, it is required to be smooth and free of burrs, and the weld seam should be processed at the same time. After welding, leak detection is required. Specifically, DF6 leak detection equipme...

Abstract

The invention discloses an assembly process of a sulfur hexafluoride gas density relay. The assembly process of the sulfur hexafluoride gas density relay comprises the following steps: assembling a measuring assembly wherein the measuring assembly comprises a first measuring element and a second measuring element, the first measuring element comprises an air passage communicated with sulfur hexafluoride gas in the circuit breaker, the second measuring element is used for measuring environmental parameters in the air passage, a measuring end of the second measuring element is communicated withthe air passage, and the first measuring element is fixed in a first cavity of the mounting shell; assembling a circuit element: fixing a junction box with the circuit element on the outer side of themounting shell, wherein a circuit in the junction box penetrates through the mounting shell and enters the mounting shell; installing a display assembly, wherein the display assembly is assembled onthe first cavity and is electrically connected with the first measuring element. The assembly process is simple in process, and can achieve the installation of two types of measurement elements at thesame time.

Description

technical field [0001] The invention belongs to the technical field of instrumentation monitoring in electric power systems, and in particular relates to an assembly process of a sulfur hexafluoride gas density relay. Background technique [0002] Sulfur hexafluoride circuit breakers are high-voltage electrical appliances widely used in power systems. The reliable operation of sulfur hexafluoride circuit breakers has become one of the most concerned issues for power supply and utilization departments. The insulation and arc extinguishing performance of sulfur hexafluoride circuit breaker depends to a large extent on the density of sulfur hexafluoride gas, so the monitoring of the density of sulfur hexafluoride gas is particularly important. [0003] Most of the existing density meters used to monitor SF6 circuit breakers are realized by monitoring temperature and pressure; most SF6 gas density relays in the prior art are measured by purely mechanical pressure measurement met...
