Embodiment
The job site of buried transformer in melt pit, work under bad environment, moist, dust is many, and the low pressure outlet terminal is a low-voltage, high-current, has danger, so require low pressure outlet cable is sealed, can water proof and dust proof.Therefore, the utility model provides a kind of sealing low pressure outlet Seal of Cables seat
As shown in Figure 1-Figure 3, be one to have the buried transformer of seal receptacle, low pressure outlet terminal B at buried transformer A top is sealed by a seal receptacle, the sealing seat comprises a seal receptacle housing 1, its side is provided with 4 wire holes 2, described wire hole 2 has seal 3 (as shown in Figure 4), and low pressure outlet cable 4 is drawn from described seal receptacle housing 1 by described wire hole 2.Owing between low pressure outlet cable 4 and wire hole 2, have seal 3, can when low pressure outlet cable is drawn seal receptacle, guarantee the sealing in the seal receptacle.
Low pressure outlet cable 4 is installed for convenience, and seal receptacle also comprises a cover plate 5, and itself and housing 1 flexibly connect, and uses the sealing ring sealing.Flexibly connecting most typical mode is to adopt bolt to connect.
After seal receptacle housing 1 is fixed on the panel of buried transformer, low pressure outlet terminal B just is housed in seal receptacle housing 1 the inside, when low pressure outlet cable 4 being installed for low pressure outlet terminal B, requirement can be opened seal receptacle housing 1 and is convenient to operation, as shown in Figure 3, seal receptacle cover plate 5 promptly is a baffle plate of sealing the operating space.Seal receptacle cover plate 5 is to be connected with bolt with seal receptacle housing 1, and its connecting portion has the sealing ring sealing, makes things convenient for the maintain and replace of low pressure outlet terminal 2 and low pressure outlet cable.
As Fig. 3, observation window 6 is arranged on the seal receptacle cover plate 5.Can be under the situation of needs, observe situation in the seal receptacles by observation window 6, check low pressure outlet terminal B and whether intact, whether operate as normal with being connected of low pressure outlet cable.Observation window 6 is the water white transparency material, and the handled easily person observes, and the connecting portion of observation window 5 and seal receptacle cover plate 6 is for being tightly connected.
As shown in Figure 4, be an embodiment schematic diagram of seal 3, Fig. 5 is the cutaway view of Fig. 4.
Seal 3 comprises: base 31, chucking sealing ring 32, clamping element 33 and retaining element 35.Wherein, described base 31 is the split setting with housing 1, and base 31 is the base that has through hole 311 in the middle of the middle tool, is provided with a circle baffle plate 312 on outer circumference surface, and is provided with screw thread on outer circumference surface.Described base 31 is arranged in wire hole 2, be enclosed within on the housing 1 by baffle plate 312, its axial two ends lay respectively at constitute seal receptacle housing 1 inside and outside, low pressure outlet cable 4 is drawn from described seal receptacle housing 1 inside from described through hole 311.
Chucking sealing ring 32 is set on described low pressure outlet cable 4 outer peripheral faces, offsets with the axial end of base 31; And by a clamping element 33, as going up threads engaged on nut and base 31 outer circumference surfaces, will tighten sealing ring 32 and be clamped on outlet cable 4 outer peripheral faces, make the space sealing between the Office of Foreign Affairs and the outlet cable 4.
Better, for the enhanced leaktightness effect, between clamping element 33 and baffle plate 312, be provided with sealing ring 34.
Because the base 31 in the present embodiment is the split setting with housing 1, for base 31 is fixing with housing 1, also comprise a retaining element 35, the opposite side that it is arranged on housing is used for described base 31 is fixed together with seal receptacle housing 1.
