Abstract
The invention provides a SF6 density relay. The SF6 density relay comprises a relay body, a shell, a temperature sensing element, a pointer type indicating panel and a sensing element, and is characterized by also comprising an alarm and signal device to improve the safety of equipment. In addition, a joint of the SF6 density relay is detachable, so that the joint can be matched with switches of different specifications for use according to requirements of users; thus the SF6 density relay has a wider application range. The sensing element in the relay consists of a spring tube and a bimetallic strip; the shell is made of stainless steel and is thereof water-proof and moisture-proof; and the service life of a product can be prolonged while the stability of the product is improved; the alarm and signal device makes a judgment according to an output gas pressure value; and the pressure value can be self-set according to the requirements of the users.
Description
Technical field
The present invention relates to relay, especially relate to a kind of SF6 density monitor.
Background technology
The SF6 electric equipment products have been applied in power department, industrial and mining enterprises widely, have promoted the fast development of power industry.The reliable and secure operation that guarantees the SF6 electric product has become one of vital task of power department.The arc-extinguishing medium of SF6 electric product and dielectric are sulfur hexafluoride gas, can not leak gas, if leak gas, just can not guarantee the fail safe that sulphur hexafluoride is electric.Seem particularly necessary so detect the sulfur hexafluoride density of SF6 electric product.
Summary of the invention
Purpose of the present invention just provides a kind of SF6 density monitor, and its directly perceived, stable density to SF6 gas is controlled and shown, has improved the fail safe that the SF6 electric product uses.
In view of above purpose, the invention provides a kind of SF6 density monitor, a kind of SF6 density monitor comprises relay body, shell, temperature-sensing element, pointer indicating dial and sensing element, it is characterized in that also comprising:
Report to the police and signalling, when gas leakage takes place, capable of automatic alarm;
Joint, this joint has two to three kinds of contact, and normally-open normally-close is optional.
Further, this sensing element is made up of bourdon tube and bimetal leaf; The shell of this SF6 density monitor is made up of stainless steel, and is waterproof and dampproof, prolonged useful life; It is reported to the police and signalling is to judge that according to the gas pressure value of output force value can set up on their own according to user's needs; Its described joint is detachable, can be supporting according to user's the switch that requires variant model.
Description of drawings
Fig. 1 is the structure chart of SF6 density monitor of the present invention.
Embodiment
Be the structure chart of SF6 density monitor of the present invention as shown in Figure 1.This SF6 density monitor the invention provides a kind of SF6 density monitor, and a kind of SF6 density monitor comprises relay body, shell, temperature-sensing element, pointer indicating dial and sensing element, it is characterized in that also comprising:
Report to the police and signalling, when gas leakage takes place, capable of automatic alarm;
Joint, this joint has two to three kinds of contact, and normally-open normally-close is optional.
Further, this sensing element is made up of bourdon tube and bimetal leaf; The shell of this SF6 density monitor is made up of stainless steel, and is waterproof and dampproof, prolonged useful life; It is reported to the police and signalling is to judge that according to the gas pressure value of output force value can set up on their own according to user's needs; Its described joint is detachable, can be supporting according to user's the switch that requires variant model.
SF6 density monitor provided by the invention is a kind of checkout gear of SF6 gas density, and above embodiment is only in order to explanation, and unrestricted technical scheme of the present invention.Those of ordinary skill in the art is to be understood that: the present invention is made amendment or is equal to replacement, and do not break away from any modification or partial replacement of the spirit and scope of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
