Abstract
The utility model relates to a new type high voltage measuring box, comprising a high voltage combined transformer which comprises a hermetic box, a high voltage terminal, a low voltage leading-out terminal, a voltage transformer and a current transformer. The voltage transformer and the current transformer are positioned in the same hermetic box, between which the insulation medium with sulfur hexafluoride gas as the main composition is filled. In the utility model, the insulation medium with the sulfur hexafluoride gas as the main composition is used, reducing quality dramatically and facilitating moving. The sulfur hexafluoride gas has great properties of stability, insulation, arc-suppression, non-inflammability, small expansion under heat, security, resistance to short circuit and avoidance of fire. In addition, the utility model has simple structure and reasonable layout with a manometer positioned on the hermetic box to check the gas pressure in the hermetic box and staff can infer whether the insulation medium gas is sufficient in the hermetic box by the numerical reading of a manometer.
Description
1, technical field:
The utility model relates to a kind of novel High-voltage measuring box.
2, background technology:
General High-voltage measuring box is made up of high pressure combination transformer part and electric energy meter metering section, and its mesohigh combination transformer part is many with the insulating medium of insulating oil as inner mutual inductor.But because oil body is heavier, cause the batch meter quality to weigh and difficult, cost also increases thereupon.Simultaneously, mutual inductor when work temperature variation big, insulating oil easily is heated and splashes bloatedly, when the leakproofness of casing became relatively poor because of reason such as aging, insulating oil easily dripped and oozes, and the oil body that leaks out has become the important source of initiation fire.If when product had internal fault, insulating oil was sharply splashed bloated even can be caused an explosion accident.
3, summary of the invention:
The purpose of this utility model provides that a kind of weight is lighter, simple and reasonable, a kind of novel High-voltage measuring box of performance safety.
The utility model is achieved by the following technical solution:
A kind of novel High-voltage measuring box, comprise high pressure combination transformer part, this high pressure combination transformer partly comprises airtight casing, high-voltage terminal, low pressure leading-out terminal, voltage transformer (VT) summation current transformer, it is characterized in that: voltage transformer (VT) and current transformer place in the same airtight casing, are full of the insulating medium that principal ingredient is a sulfur hexafluoride gas between airtight casing the inside voltage transformer (VT) and current transformer.
On the above-mentioned airtight casing tensimeter is housed, tensimeter communicates with closed box spare the inside.
In the above-mentioned airtight casing, voltage transformer (VT) is positioned at airtight casing central authorities, and two current transformers are positioned at the voltage transformer (VT) both sides.
Above-mentioned voltage transformer (VT) is spliced by two single-phase transformers.
Above-mentioned current transformer is made up of two single-phase transformers.
The capping of big or small full skirt porcelain vase is arranged on the above-mentioned high-voltage terminal.
Above-mentioned high-voltage terminal and low pressure leading-out terminal all have capping, make anti-electricity-theft usefulness.
The utility model compared with prior art has following advantage: 1) the utility model with the principal ingredient be the gas of sulfur hexafluoride as the major insulation medium, make the product of insulating medium with respect to insulating oil, quality obviously reduces, convenient in carrying.2) sulfur hexafluoride gas has good stable, electrical insulating property and arc quenching characteristic, and is nonflammable, and splashing after gas is heated expands changes not quite, can not cause situations such as fire, relatively safety.3) the utility model applied voltage mutual inductor utilizes two single-phase transformers Mosaic faces to become, and simple in structure, anti-short circuit capability is strong; Voltage transformer (VT) is placed central authorities in the airtight casing, and two current transformers are positioned at the voltage transformer (VT) both sides, have also saved the space, and are rationally distributed.4) on the airtight casing tensimeter is housed, tensimeter is used for detecting the gas pressure intensity in the closed box, and the staff can infer whether insulating medium gas is sufficient in the airtight casing by manometric reading.
