Description
Technical field
The utility model relates to a kind of stationary installation for fixing GIS disconnector stroke measurment sensor.
Background technology
Along with the development of global power system self and the raising day by day to system operation reliability requirement, SF6 combined electric appliance equipment (GIS) is popularized gradually in current electric system, it has volume little, floor area is few, dielectric strength is high, safeguard the advantages such as simple, GIS disconnector structure mainly comprises: disconnector be located at fill SF6 gas closed shell in, stretch out outside housing outside the rotating shaft head that driving isolation switch separating brake closes a floodgate, adopt machinery, pneumatic or hydraulic connecting rod mechanism clamps from housing and rotating shaft head just can disconnector separating brake in drive shell or combined floodgate, certainly, require during rotation that rotational angle must meet required angle, otherwise the separating brake of disconnector or combined floodgate will not be thorough.
But in recent years, because it cannot the defect of disconnector divide-shut brake situation in visual inspection housing, cause several accidents, as two grid event-Shenzhen 4.10 occurring in Guangdong Power Grid Corporation's system and horizontal drop 4.11 event, all cause because switchgear stroke is undesirable.
The I&M of the disconnector of current conventional open style has out the requirement such as distance and contacting travel, but to test method only just withstand voltage test and the loop resistance test of GIS disconnector opening and closing state, test the dielectric level (opening distance) of both sides fracture under disconnector gate-dividing state by withstand voltage test whether to meet the requirements, if but open apart from when being changed to 100-80mm by original 120mm, conventional withstand voltage test cannot detect; Under testing detection and isolation switch "on" position by loop resistance, whether both sides contact contacts well, but as: when contacting travel is changed to 10-8mm by original 35mm, conventional loop resistance test can't detect; So these two pilot projects all belong to qualitative test, the actual conditions of not energetic detection GIS disconnector.So cause concern gradually about the performance standard problem such as stroke of GIS disconnector I&M.The fixed support that can design an installation stroke survey sensor on the disconnector of SF6 combined electric appliance equipment (GIS) that solves the problem carries out stroke measurment with fixation of sensor to GIS disconnector, because stroke measurment sensor is for measuring breaker trip, it not the standard outfit of GIS disconnector, both structures are different, GIS disconnector does not design the installation site of sensor, so sensor cannot be arranged on GIS disconnector, redesign to manufacturer, cost is done rather; In addition, must it is mentioned that, stroke measurment sensor has certain weight, and support it must need certain structural strength, to make between its with equipment fixing firm and vertical.
Utility model content
Technical problem to be solved in the utility model, is just to provide a kind of stationary installation for fixing GIS disconnector stroke measurment sensor.
Solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
For a stationary installation for fixing GIS disconnector stroke measurment sensor, stretch out outside GIS housing outside the rotating shaft head of described GIS disconnector, it is characterized in that: described stationary installation comprises:
