Abstract
The utility model relates to a kind of high-voltage contact box for metal closed switch cabinet remote visible, and this contact box comprises: bus connecting bolt, radio temperature sensor, camera, fixed contact, contact box housing; The cylindrical structure of whole contact box housing, bus connecting bolt is positioned at the outer tip end of high-voltage contact box, is connected with bus; One end of fixed contact is fixed on the inner face near the contact box housing of bus connecting bolt, and the other end is free end, contacts with moving contact; Described radio temperature sensor is sleeved on the outer surface of fixed contact; Described camera is positioned at the oblique upper of fixed contact and is fixed on contact box housing.The utility model high-voltage contact box is not only simple in structure, safe and reliable, and can omnibearingly monitor contacting and disconnection situation of moving contact and fixed contact, temperature rise when measurement moving contact contacts with fixed contact changes, and has avoided as much as possible the phenomenon of burning switchgear producing because temperature rise is too high.
Description
Technical field
The utility model belongs to dynamo-electric manufacture field, particularly a kind of high-voltage contact box for metal closed switch cabinet remote visible.
Background technology
Power equipment safety reliability is the important step that ultra-large power transmission and distribution and power grid security ensure, along with fast economic growth, the power supply of national grid load increases day by day, brings a series of safety problem also to electrical network electric equipment simultaneously.Whether national standard requires high-voltage switch electric appliance should have obvious air insulated to open circuit always, because the dynamic and static contact in high-voltage switch electric appliance connects, be reliably the key factor that affects power grid security.In traditional switch cubicle, only having fixed switching cabinet to adopt isolating switch to realize obvious air insulated opens circuit.High voltage switchgear because of the dynamic and static contact of primary cut-out bad, add that the factors such as long-term large electric current, contact are aging easily cause its contact resistance to increase, thereby cause that long-time heating, contact temperature rise are too high, and the phenomenon that switch cubicle burns even finally occurs, have a strong impact on the safety of electrical network.
Utility model content
For overcoming above-mentioned defect, the technical problems to be solved in the utility model is to provide a kind of simple in structure, safe and reliable remote visible high-voltage contact box that is applied to metal closed switch cabinet.
For a high-voltage contact box for metal closed switch cabinet remote visible, this contact box comprises: bus connecting bolt, radio temperature sensor, camera, fixed contact, contact box housing; The cylindrical structure of whole contact box housing, bus connecting bolt is positioned at the outer tip end of high-voltage contact box, is connected with bus; One end of fixed contact is fixed on the inner face near the contact box housing of bus connecting bolt, and the other end is free end, contacts with moving contact; Described radio temperature sensor is sleeved on the outer surface of fixed contact; Described camera is positioned at the oblique upper of fixed contact and is fixed on contact box housing.
Described contact box shell material can be selected polymethyl methacrylate, tempered glass or fiberglass.
The utility model high-voltage contact box is not only simple in structure, safe and reliable, and can omnibearingly monitor contacting and disconnection situation of moving contact and fixed contact, temperature rise when understanding moving contact contacts with fixed contact changes, and has avoided as much as possible the phenomenon of burning switchgear producing because temperature rise is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model high-voltage contact box.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, a kind of high-voltage contact box for metal closed switch cabinet remote visible, comprising: bus connecting bolt 1, radio temperature sensor 2, camera 3, fixed contact 4, contact box housing 5.The cylindrical structure of whole contact box housing 5, bus connecting bolt 1 is positioned at the outer tip end of high-voltage contact box, is connected with bus.One end of fixed contact 4 is fixed on the inner face near the contact box housing 5 of bus connecting bolt 1.The other end is free end, contacts with moving contact.Radio temperature sensor 2 is sleeved on the outer surface of fixed contact 4, the variations in temperature in the time of fixed contact 4 can being detected to greatest extent and contact with moving contact.Camera 3 is positioned at the oblique upper of fixed contact 4 and is fixed on contact box housing 5, fixed contact 4 and the connection state of moving contact can be reacted to remote control center.The material of contact box housing 5 can be selected polymethyl methacrylate, tempered glass or fiberglass.
The utility model has been developed remote visualization and the transparent contact box of temperature monitoring for the deficiencies in the prior art, this contact box is for metal closed switch cabinet, the disconnection that can monitor fixed contact in moving contact in high voltage breaker and switch cubicle be connected, can monitor the variations in temperature of fixed contact junction in the true moving contact of breaker of high pressure and switch cubicle, thereby improve the security reliability of electrical network for distribution.
