Description
Technical field
The invention belongs to substation equipment maintenance and repair technical fields more particularly to a kind of disconnecting link with angle limit to open away from adjustment fixture.
Background technique
High voltage isolator is three-phase alternating current 50Hz outdoor high-voltage electric appliance, is used for voltage rating 12kV and power train below
In system, for route it is zero load have voltage in the case where switch over, and to electricity such as the high voltage bus and breaker overhauled
Gas equipment carries out electric appliance with alive circuit and is isolated.Disconnecting link open away from refer to switch or breaker in open position, dynamic/static contact it
Between minimum range.The disconnecting switch of three-phase ganged, when contact, three it is corresponding keep synchronizing, apart from identical, after combined floodgate,
Insertion depth is consistent, just meets the technical stipulation of product.
Especially 10 kilovolts of second disconnecting links of substation, as route outlet disconnecting link, because long-time is in outdoor application, driving section
Part usually corrodes the defects of serious, support insulator weathering fracture, overload and poor contact cause conducting position fever scaling loss, pole
The big normal operating condition for affecting equipment, causes the line facility to be usually forced interruption maintenance.Since 10 KV line are more
For residential electricity consumption, public utilities electricity consumption etc., seem extremely difficult to the arrangement of power off time, it is desirable to overhaul teams and groups to 10,000
The installation of second disconnecting link, maintenance, debugging etc. is lied prostrate to improve working efficiency in the process, shorten power off time.
Disconnecting link in installation, in maintenance process, disconnecting link open away from debugging be an important link, open carpenters square cun and be adjusted in place
Disconnecting link and the joining beam of mechanism can be welded in the operator shaft of disconnecting link by connecting lever, this seems simple work, if any touching
Head is opened away from position is not measured, and just mechanism joining beam is welded in operator shaft, it may appear that mechanism is in manual point, closing operation process
In, the operation incomplete phenomenas such as stroke is too short or too long, making entire disconnecting link debugging efforts, all that has been achieved is spoiled；Disconnecting link open away from less than
Position, open away from it is excessive when, disconnecting link closure, due to contact hardness power it is inadequate, cause contact to overheat, enlarged contact resistance causes contact
Overheat or even melting welding or scaling loss.Open away from it is too small when, electric insulation distance not enough, may cause arcing or ground connection.
In conclusion disconnecting link open away from adjustment, directly affect the operating status and service life of disconnecting link, or even influence
The safe and reliable operation of grid equipment.Just there is an urgent need to one kind to open away from adjustment special mould clamp for this, can open disconnecting link away from rapid adjustment
In place, it improves efficiency, shorten the repair time.
Summary of the invention
The present invention in order to solve the problems in the prior art, provides a kind of disconnecting link with angle limit and opens away from adjustment fixture,
