Description
Technical field
The utility model belongs to breaker technical field, is specifically exactly to be related to being monitored circuit breaker internal temperature
Device, more particularly, to breaker temperature acquisition device mounting structure.
Background technique
In general, breaker is mounted in the electric protective device between power supply and load unit, with protect such as motor,
The load unit of transformer and power transmission line protects it from the circuit of such as power transmission/distribution line and private transformation facility
The damage of the abnormal current (i.e. the high current as caused by such as short circuit and ground fault) of generation.Breaker is in normal use situation
Under circuit can be opened or closed, also can use motor-operating mechanism from the power transmission line is opened or closed at a distance, and in mistake
Block (break) described power transmission line to protect electric power facility and load unit automatically when electric current and short circuit.
Breaker carries electric current in closure, at this time the temperature highest of moving contact and static contact contact position.When breaker
When temperature is more than safe range, the safety of breaker may be reduced, or even damage.Therefore the temperature to circuit breaker internal is needed
Degree is monitored, it is especially desirable to which the temperature at the contact of monitoring breaker makes user find that breaker temperature is excessively high early, in time
Take counter-measure.

Between be provided with a cavity, temperature sensor is located in the cavity.There is plastic part lid between static contact and temperature sensor
Plate, can fixed temperature sensor, prevent from falling off, while, it can be achieved that temperature sensor mutually insulate with static contact.The breaker temperature
The temperature sensor of detection device is spent in the cavity between static contact and bottom plate, so mounting temperature sensor is inconvenient,
It is unfavorable for increasing temperature-monitoring function on existing breaker.And plastic part lid is increased between static contact and temperature sensor
Plate makes temperature sensor mutually insulate with static contact, and temperature sensor is not the contact temperature directly contacted, therefore measure with static contact
There is also have error for degree.Temperature sensor is not directly contacted with static contact in the breaker temperature detection device, main to consider
Factor in terms of following two, first is that due to the insulating requirements of temperature sensor, due to temperature sensor long-time and major loop
Contact, if the insulation performance of temperature sensor does not reach requirement, in the case where long-time bears main circuit voltage, insulation can
Energy can be breakdown.Second is that safety requirements when maintenance.In maintenance, service personnel may touch the conduction of temperature sensor
Part.If the static contact of temperature sensor and major loop directly contacts, in the case where breaker open operation, due to static contact
Directly it is connected with power supply, the current-carrying part of temperature sensor is electrification, dangerous to service personnel.And moving contact is due to being living
Dynamic component, it is difficult to be mounted directly temperature sensor.
